Jim said his doesn't have the reservoir nor the check valve, so I wonder if that is an '87 and later thing. On the diagrams, I think I have a book of diagrams that I've not scanned in, so if you have those post them, please. That's another area we could flesh out. We have some diagrams, but not all.

Bill - Does Darth have the vacuum reservoir for HVAC and the check valve?

Yes, back to the cybertruck.

Your truck is WEIRD! So, it has both an '87 frame and '87 door strikers? What else? What was the production date on it?

Aren't you glad you took it apart!!!! Gonna shift lots better with those pads on the forks. In fact, you are lucky it shifted at all. Had an NP208 w/o the pads and it wouldn't go into 4LO. Just couldn't move things that far w/o them. And, you got the drive gear swapped. Tranny ought to be much smoother, shouldn't leak, and the speedo ought to work to boot. Is it about time for a Bloomin' Onion?

Yes, that and the fact that there were multiple plants building these trucks in at least two different countries;). What I find on the Canadian built trucks up here may not always be 100% indicative of what came out of the various plants in the USA. I know that generally they are all the same, but there will be little quirks and differences here and there for sure. The ones I've found on the later 1994-1996 trucks have crisp 7/16" threads in them. Enough so that a regular bolt threads into them nicely. Otherwise they are identical in every respect. A lot of things can change over the years too, so it is possible that I've come across a batch of trucks that all had had their door strikers replaced? Who the heck knows. Cory - Ford appears to have either gathered the extra/leftover parts from all the factories and shipped them to just a few plants, or if the just-in-time delivery idea was in place then they had the unused parts that were still at the manufacturer shipped to just a few plants. You can see that in what we figured out on the door locks here: Documenation/Interior/Doors/Door Locks. In other words, as new things were phased in the old things came out of a few plants and the new things out of the other plants. So it may be that the plant in Ontario was an early adopter?

I've not put the HVAC hose to the carb, but it will work. The manifold vacuum off the manifold is the same as the manifold vacuum port on the carb. In fact, if you pull the carb and trace that port you'll see it makes a 90 and goes down into the manifold. But, you have ported/timed and manifold vacuum backwards. Manifold vacuum is there all the time, but timed or ported vacuum is not there at idle and comes in as you open the throttle slightly. I like timed vacuum for the vacuum advance. The vacuum diagrams Jim referred to are here: Documentation/Underhood/Vacuum Systems/Vacuum Diagrams/460 V8. Jim - The EVTM doesn't differentiate by engine. The vacuum diagram is shown below, and that's the same setup Big Blue has. Perhaps the '87 and later ones have the vacuum tank and check valve built into the system in the cab?

Yep, they're also captive, and they have a thin metal washer behind the guard. Build date is March, 1990. I don't know what they changed in 1989 but the ones from the 90 look just like the ones from 86. I suspect that we are dealing with the fact that Ford never threw a single part away. So if they had some of the ~86-88 strikers still available they went on the vehicles rolling down the line - whatever year that was. If I'm right on that, a 1990 could have gotten a 1986/88 striker.

If the only thing w/o manifold vacuum is the HVAC system just plug it into the manifold vacuum port on the front driver's side of the carb, as shown in Figure 1 in the Edelbrock installation manual. But, as was said, you do need the check valve/tee and vacuum reservoir shown in the Vacuum Systems pics or your HVAC system will default to Defrost when the vacuum goes away with heavy throttle. As for the ones on the thermostat housing, they are temperature controlled and were part of a complex system to provide vacuum for various emissions systems at specific temps. Since you have an aftermarket carb and no belt on the AIR pump I'm guessing you aren't worried about emissions. In that case I would remove those valves and plug the holes with pipe fittings. Then I'd set my vacuum advance up with ported vacuum from the timed port on the Edelbrock carb, which is the port on the front passenger's side. And if you aren't using the thermactor system we can talk about how to remove it.

That's strange. Here's what I see on the Driveshaft page and on the U-Joint tab:

There appears to be 3 different striker assemblies. There are the Bullnose ones...just the striker bolt with a captive washer, from 1980-1986, although the changeover date/time may vary. 1987 got the striker post with the wrap around steel guard, and it was also captive, just like the washer on the Bullnose. You cannot remove the striker bolt without damaging the threads. At some point after 1987, they changed the guard from being captive on the striker bolt to being threaded, and then added a thin plastic washer behind the guard. I don't know when this change took place, I just assumed it was 1992 with the body style change. If you look at the aftermarket striker on JBG, it shows that it is a replacement for Ford part # E9AZ-5422008-A, which tells me that it probably changed in 1989 or 1990? Or else it would have had an E6 or E7 part number, correct? https://shop.broncograveyard.com/1987-1997-Ford-Bronco-and-F-Series-Truck-Metric-Door-Striker-Each/productinfo/34385A/ The junkyard I go to most often has a whole bunch of 1994-1996 F trucks, and of all of them that I checked, the striker bolt threads out of the steel guard on them. I actually took 3 of the strikers from these trucks to swap in later on (2 to use, and 1 for a spare). The only Bricknose trucks that were there were both 1987's, and they both had the strikers with the wrap around steel guards, but the striker bolts could not be removed. It seems like too much of a coincidence to me that all of the later ones I looked at were threaded into the guards, but who knows. Anything is possible. Cory - I think you are right on all counts. Here's what the MPC says about striker bolts and the part number JBG lists, E9AZ 5422008-A, fits our trucks as it shows "80/89" meaning 1980 - 1989. And the E9 means it was new in 1989. But, the "A" of E9AZ indicates that the part was originally designed for the full-sized Ford cars. Which caused me to pull up the 1980/89 passenger car MPC. Turns out that striker bolt was used on LOTS of things. So they ought to plentiful!

Jim - I'm confused. There's not supposed to be a Driveline/U-Joints. But there is a Driveline/Drive Shafts and that page has a U-Joints tab, which works for me. What am I missing?

I like the use of the shop crane to pull them apart. I learned something new. Yes, we need a thread, or maybe a page, that tells how to take them apart AND put them back together.

But others find that taking the guard off on some of them is easy. So what's the difference?

Well done, Scott. I had no idea there were that many different A/C installations.

Ok, I'm confused.

Yes, fixing a cracked firewall can't be fun. I'm not sure what clutch is going in BB this round, and it might put more pressure on the linkage/firewall.

Did not realize that there were 5.0L water pumps on serpentine systems that rotate both CCW and CW. Confusing.

I guess I'm not understanding. What would be the advantage of finding a thread that somewhere in it there's at least one instance of your search result? You'd then have to search in that thread for the instance(s). Wouldn't it be better to find every post that has your search term on the first search? And by the way, I've already modified the search function to take the signatures out of the search because if you search for something that's in my sig you'll get 13,000+ hits.

Yes - here's where to find the 1985 EVTM: Documentation/Electrical/EVTM/1985 EVTM. The basic vacuum diagram is show on #32 Vacuum, and the HVAC vacuum diagrams are on #35 A/C Heater.

Shaun - So there are at least three versions of the striker? Is that about right?

According to the TSA the small ones are adequate if the firewall isn't already cracked. But I have a big Terrapin so think I'll put it in Big Blue even though his firewall doesn't appear to be cracked.

Sam - If you do a basic search for alternator you'll find any post that contains that word in the body, and any post that contains that word in the title. However, after you type the search term in you'll be offered an option to do an Advanced Search, and if you click that link you'll see the screen below. If you enter the search term in one of the fields in the Message Text Contains section you'll get much better search results. Does that help?

It turned out that the pan on Huck's engine uses the dip stick with an o-ring. So I'm using it. But I do have the one-piece pan gasket. By the way, those valve covers look great!

Looks like you installed a later striker bolt? One with the guard? Can't tell, but did you do the PEX upgrade?
