Gary has posted the drawings and part numbers in the WHYDTYTT thread.
The parts are definitely different '65-77 and '77 on.

But your I-6 pivot doesn't have anything but concentric radial features Dave.
A replacement could pretty easily be turned on a lathe.

If you had a drawing or the G-code you could sent it off to any machine shop.

Jim,
Lil'Red is a '87 F250 HD, 4.10's, 1356 4x4, Zf-5, 3G, PMGR, Saginaw PS, desmogged with a Holley 80508 and Performer intake.
Too much other stuff to mention.

Thanks Jim I seen it and posted.
If I can find the good one I may give the machine shop that messed up the king pin bushings a 2nd try if the price is not to bad.
I can also do a Google search to see if there are any others I have not been told of and maybe 3D printing of them?
Just need good one to take measurements from is all

Re: 81 F100 flare side custom with 300 six & T18

Good new, bad news & badder news.
Good news: I found the NOS part and got measurements from it. 3" long my fixed one is 3.25" long, too long but I had nothing to go by when I fixed it.
Bad news: I figured I would use the fixed one so I could use the NOS to have others made off of. I think I saw why it broke, the threads were either too long and bottomed out or the weld would not let it seat on the nut part of the pivot like the base on the NOS one.
Badder news: In trying to get the fixed one to sit on a flat base I ground down the weld and was using a die to thread it down a little more and the welded threads that my son said was better than mine failed also leaving the threaded part in the die.

So I had to use the NOS part on the truck and will try and fix the fixed one again and see if i can have someone make a few if not to much $$$.
Also when I pulled the linkage Ford uses thin plastic bushing between the rod ends that go thru the firewall. They were new when the truck was put on the road little over 2 years ago, they fell apart when I took the linkage apart.
So I had to hit the hardware store for something better but they did not have anything that would fit either the rod or the hole it went thru so I had to make them.

The good is they are thicker and little tougher so I hope last longer and I got extras and it is not to bad now that I know what has to be done to make them work.

I also looked for the new / broken mirror head, glass broke when wife backed over the box from LMC, I must have thrown it out
SO the truck now moved so if I need to use it I can.

Yes it is, that one you cant get any more

You can get the plastic bushing, the felt seal even the clip that holds the bushing on but not the screw in pivot.

The NOS one I got years ago, I think a member found on Ebay so I grabbed it ASAP.
Up till this morning I could not find it and I was freaking out on how I was going to fix this.
It was in a box with 2 3 port fuel switching valve (also hard to get) and the inside door handle gaskets Gary sent me with my AMC parts LOL

I think the fact that it wouldn't seat down against the base is what caused the old one to break. No matter how good the welds, focusing the force right on the spot where it clears the block is a bad thing.

Hopefully the NOS one went down against the block as that will make it much stronger.

Yes it did and think you are right about it not seating as I checked the fixed one before I broke it and the NOS one when I installed it.

I have nothing to loose drilling and tapping for 9/16 threads like you said. I never gave that a thought other than driving a roll pin in like I did.

Up date:

Back on the 11th had a show a few towns away, truck made it there and back just fine.
As I was driving it it dawned on me that the clutch pivot must have been going bad for a bit as the pedal did not come up all the way before it broke, had to pull it up with your toe.
Clutch worked great.

Still waiting for the replacement mirror from LMC.
The mirror I barowed would not adjust so its pointing to the moon LOL
Cant wait for the new mirror as I drive with it and I am lost with out it

Dont know if we have a show this weekend or not but its going to be really hot even in the shade and who wants to sweat in the shade?

Re: 81 F100 flare side custom with 300 six & T18

Well a little up dating:
I got the mirror and mounted it. I am not real happy as it moves when ever you close the door.
I have tighten up the 3 screws on the bottom but worry if I go to tight and I adjust it (and hope it stays put) I could snap the mount like the first one.

Back a week or so I messed with the AC on the truck, replaced a o-ring that was leaking.
Pulled vacuum for 45 min. then held it for 45 min and loss 2 psi.
I then pulled vacuum for little over an hour and tried to charge the system.
It only took part of 2 cans, could not get the system low above 20 psi and the high was 155 psi.
I gave up as it was hot and it not taking the charge like it did when I first got the system working.

To day I was able to add the rest of the 2 cans by soaking them in hot water.
I even added a 3rd can and the low came up to 30 psi and the high to 150 psi at 800 rpm.
Bringing the RPM up to 2500 the low dropped to 25 psi but the high stayed at 150 psi.

I believe the used junk yard compressor I installed when first getting the system working is bad as the high side dose not go up with RPM.
I ordered a compressor, evap coil & dryer, I have a new orifice valve and will replace ALL O-RINGS when I replace the parts and

it works and stay working this time!

I hope the new stuff solves the A/C problem for you, Dave. On the mirror, have you thought about Loctite on the adjustment? I've used it on things like that before and it has worked.

Re: 81 F100 flare side custom with 300 six & T18

On the AC me too.

Mirror if I add the Loc-tite if it makes it so I cant move / adjust it before it sets up it will snap it again.
I am sure I can tighten the screws but again if to tight it may break again.

What product did you use?

I used Blue. It held it enough it didn't adjust when I closed the doors. But if you then adjust it you'll have to hit it with Loctite again. And IIRC, I took the mirror off and dribbled the liquid down into the ball.

In reply to this post by FuzzFace2

I was thinking that clutch pivot could be easily made and maybe even improved on. A good machine shop could fabricate it.

Good luck on your AC fix Dave. Agree that it is likely your compressor. Where did you purchase a new compressor from?

If it really gets to me I may give that a try.
Again just worried when I get the mirror back on and I know I will need to adjust it it will snap the mount.
I will have to take a picture if I can of the one that broke as there was not a lot of meat of the part that broke.

On the clutch finding a "good" machine shop is the problem.
The only one around is the one that messed up the kingpin bushings and now that I dont have a NOS one they can take measurements from or a blue print to go off of they would have a fit I bet.

If I was thinking before I needed the NOS one I used I should have made blue print drawings so someone would have something to go off of

Maybe I will get lucky and someone will find one for a good price on Ebay I can get and then see if they can make a few but I am not going to hold my breath LOL

I went with Rock Auto.
I have a miss matched of parts to make the system whole.
The evap coil, dryer, condenser and some of the hoses are 81 but the compressor is for a 85 300 six with a vbelt.
Because of the 2 different years of parts is why some hoses are for 81 and others for the 85.

If I went local most of the prices were higher and also had a wait time so figured why not go with Rock Auto.

Re: 81 F100 flare side custom with 300 six & T18

Little up date more than anything.
The AC has been blowing cold since July so fingers crossed it stays that way.
I would use the truck to / from work as the cab is smaller to cool off in on the really hot days.

The clutch linkage has also been good since using the NOS pivot on the block side.

Also been using it for the weekly trash runs and hitting shows and Cars & Coffee's with the car club I am am a member of.

The last show the truck marked it's parking spot. Think 1 of the heater hoses at the vacuum valve to close off water to heater core was leaking.
Out of the 7 cars the club had at the show not 1 of us had a screw driver LOL
I just loosen the radiator cap so it wold not drip and for the ride home.
And of course I for got about it before I did the trash to day

Being we are kind of locked in because of storm Ian and if I can remember I will look into it tomorrow.

I would like to change the oil as I think it is due but with the rain and no glass in the car in my garage I cant go switching them around.I have also been working 1 weekend day and shows the other and 14 hour work days dose not leave time for the truck other than shows.

Dave - Glad you got the A/C working. And hopefully you are right on the coolant leak - easy fix. Good luck!

Re: 81 F100 flare side custom with 300 six & T18

I hope I got the coolant leak fixed.
I did find 1 clamp loose. Could only get a wrench on it and a 1/4 turn at a time.

Our car club show was canceled because of the weather / rain, but there was another show 45 miles away rain or shine so off I went. It rained on & off most of the way there so I had the AC on to keep the glass clear but because it was cool out I had the temp turned up some.

When I got to the show and parked there was a big puddle from the AC, think it iced up and was melting.
So if I still had a coolant leak I could not tell.

About 40 nice cars & trucks showed up even with the threat of rain, it did not rain at the show.
I got a 2nd place but I dont know what class as they where not calling out classes, not marked on the forum or the plaque.
There was 1 90's F250 PU and 60's chevy 4x2 and a 58 Chevy 4x4, both chevy's looked like they rolled off the show room floor.

Because it was held in Mt Olive every one got a jar of Mt Olive pickles, a goody bag with the normal stuff and a baggie full of candy and a dash plaque.

I may have some new members joining our club that I talked to at the show too.
I was the only one from our club to go as some were with out power from the storm but had a good time.
