Well I have completed the perch mods. Nothing very pretty but no concerns regarding their strength.
The drill turnings look more like powder in the picture. Just need to clean up and do any painting, etc.    Getting close to be starting to put the truck back together.I just have to pull the pedal assembly and column on the donee. On the clutch linkage - wondering if anyone has switched the nylon bushings to heim joints on the long rod that transmits from the pedal arm to the z-bar arm?

Thanks Dane and Gary, I am starting to think it will all work out fine.
Gary you are absolutely right about the benefits of documenting progress on the project. Any time I think this is taking forever I just look over what has been done and it gets me excited about the project again. I painted and bolted down the engine perches and now I am getting started on the interior work. I am really happy with the condition of the floor under the carpet.    The tunnel cover from the 4 speed truck nests perfectly with the original cover and so the carpet should lay down like factory  .

Yep. And one of these days you'll be working out the little teething problems. Things will be going so well you'll have to review the documentation to realize what a huge effort it was.

Gary I am sure that you are right about all the teething problems.
There is a lot of diesel electrical to delete and then the fuel system to sort out. Anyway had a good day today. Pulled the pedal assembly on the diesel and compared them. The cruise vacuum switch brake pedal presser block does not align and I had to move it. The hose clamp holds it really well so may just leave it like that. I had to drill out the holes for the vacuum switch mount, holes were there but too small. A few points for anyone who may be doing something similar. I tied the brake booster in position when I removed the pedal bracket nuts. They are shouldered nuts and will push the booster out of the firewall when you remove the last nut - there is a plastic collar on the booster and it breaks easily on the firewall edge if one is not careful. Before I disconnected the steering wheel shaft collar I locked the steering wheel so that there is no chance of it getting rotated out of position. If the steering column is for an automatic transmission don't forget to disconnect the transmission range indicator cable. I made the cut-out for the clutch rod bellows. Nice fit for the bellows and the location seems right. I will find out soon when I start putting it all together.

Well made a little more progress. The weather has been a little uncooperative with a few rainy days.
The only bad bushing on the clutch linkage is at the down rod to the z-bar pivot. The pin is okay but the hole on the rod is elongated. I pressed in a piece of brass pipe and then drilled it to size. Not sure if it will last but I can remove the rod without too much trouble if I have to rework it.    I drilled out the holes on the exhaust manifold for the choke heater tubing - the originals were all rusted off. I then made up 1/4" copper tubes to replace the original steel. I was able to fit them so they will stay in place so hopefully that will make the choke fully release.   I installed the pedal bracket and it looks like the clutch linkage will be just fine.  I had thought about setting the engine on the perches today but the wind was really blowing too much for me to feel comfortable removing the hood. Tomorrow is another day.

Bob - You are making great progress.
That brass bushing should work fine for quite a while. But when you need to replace it you might want to get some Oilite bushings. The sintered bronze holds lubricant in the pores so lasts longer than brass itself. As for the choke, your copper tubing should last a long time and make a huge difference on the chole.

Thanks Gary, Yes I will see how long the brass lasts. I think when it wears out I will see about adapting a heim joint.
Well I got the engine sitting on its perches. It was a tight fit but by removing the weather strip at the firewall I was able to get enough clearance to drop it in without having to loosen the rad support. Something about seeing the engine in place makes me more excited about this project. I checked the fit of the z-bar and clutch linkage and it all lined up like factory so very happy about that.  Must be sure to remember the spacer plate before I put the flywheel on.

That's great, Bob!
Sure is a lot more room in there now. Happy for the progress. Hope the weather helps you along. I don't know about the mechanical clutches, but I had a shell casing on my clutch linkage with a C-clip in the extractor groove for years. When it failed I replaced it with a flanged sintered bronze bushing like Gary suggested.

Yes, that is looking good!
And I agree, getting the engine in makes it look like there's real progress happening. Keep on truckin'!

Thanks Jim, yes I love all the space to work. On clutch linkages etc. it is amazing what one can do with a little ingenuity.
The weather is good, I hate to complain but I am sure I will when it gets hotter. Thanks Gary, I felt like I was moving along nicely until I created or possibly found a problem with the pilot bearing. I went to blow it out before greasing it and one of the rollers flew out. It looked and felt alright but when I looked more closely I could see that the cage had a bit of damage. So nothing in town so had to order a new pilot bearing. I attempted to pull the bearing out of the crankshaft but all I got was the bearing itself and not the sleeve.  When I look at parts pictures of the bearing it shows the actual bearing with a sleeve and it is only available as an assembly. I am thinking that the bearing itself is probably some standard needle bearing and I am hoping that it will be possible to just replace the bearing itself as I don't have a puller for the sleeve. Has anyone else run into this?? I guess I will find out when I get the part. Lots of other things to work on in the meantime.

Well hopefully the bearing itself is a standard item and I can just press it out of the new pilot assembly and install in the existing sleeve.
In the meantime I am giving the transmission a good once over.  Low gear on the countershaft looks to be in good shape as does the reverse idler. I pulled off the PTO cover to inspect the countershaft gear and as expected found that the magnet was definitely in need of a good clean. This would be a worthwhile thing to do for anyone with a T18 or T19. I imagine the NP435 also has a magnet in it.  The only gear teeth needing dental work are on the 1st/reverse slider and I think I will try dressing them a little.

Well I finally got the pilot bearing. I picked it up this past Tuesday.
As I had hoped the bearing is a standard item, but as far as I can tell you can only buy it as an assembly with the sleeve. Anyway I pressed it out and tapped it into the existing sleeve.   It took me a lot of cleaning to get all the old mouse nest out of the pressure plate, but with a lot of picking and blow gun work I eventually got it all out.   Getting that heavy T18 into place by myself was fun. I managed to wrestle it under the truck and then decided to suspend it from a cross beam and keep adding 2 x 6s to get it up to the correct height (had to re- sling a couple of times). I then walked the beam forward and once I got it started on my guide dowels it slid into place quite easily.    I had to extend the slots in the crossmember for the transmission mount by about 3/8" but other than that everything lined up very nicely. I cleaned up and lubed up the z-bar and installed that and the clutch feels really good. Have a few things to figure out still but it feels like it is moving along nicely again.

Progress is good, Bob!
Glad to hear the gears are okay and the linkage works well.

Good job! Yes, I especially like the sling. But I was initially concerned that it would slide down the floor at the opening - until I saw the blocks at the ends and finally twigged to what you were doing.

Well the driveshaft fits and still has plenty of travel on the slip joint.
The exhausts melded nicely, not sure how it will sound with the 2" pipe feeding into a 3" aft section.  I had been trying to figure how to fit the gear shift boot and carpet. Decided on fastening the boot directly to the tunnel cover and just cutting the carpet to fit around the boot. Very happy with how it turned out, carpet fits perfectly and almost looks factory.   Slowly sorting out the engine compartment. I am going to stick with the diesel rad as it is almost new and also the rad support is in much better condition than the donor. The rad hoses are matching together fairly well using exhaust adapters to match the different sizes. I managed to put some small ridges on the adapters and I don't think there is any danger of them coming apart.  Won't be long before I can fire the old truck up and have it move under its own power.  This crazy hot weather is limiting how much I work on it each day. I am much more patient than I used to be.
