This sounds like the answer to my problem! It looks to be 1 1/4"+- too short for my bell housing. Do you have a picture if the bushing?
My memory is I figured I needed 1.25 inches long, but I had it made 1.5 inches to be safe. I had the engine, bell housing, and transmission on the floor in the garage when I did this. I installed the long bushing, bolted the bell on, and slid the transmission on. The bushing was too long and holding the transmission back (which I expected) so I took a disk sander and slowly sanded the end off the bushing until the transmission fit. This way the bushing was exactly the length I needed. Kind of crude, but very effective. I cleaned the area carefully, greased the bushing, and bolted everything together.
The only other thing worth mentioning is I had to add a bend to the 1st / rev shift rod when I installed the T-85. The shift arm spacing on the non-overdrive 3.03 transmission is wider than the T-85. This is probably not a problem for your installation. In case it is, here is a picture of the T-85 after I installed it in the '66:

I haven't done anything with mine yet, I want to keep my 56 bell housing with the rear motor mounts. if you search "T85 Overdrive" there is a posting from a guy in who had a machine shop turn down the input end, and have an extensions made up. I have to "dry fit" mine with an extra engine I have laying around. I like the thick bushing idea if it will work.

I do not have a picture of the bushing. I took the new one from my clutch kit and measured it for ID and OD. If you don't have good quality machinist measuring tools you can take the bushing from your clutch kit to the machinist making the new bushing for reference.
I was working at a machine shop when I put that truck together, but didn't have any bronze stock. It would have cost more to buy a piece of bronze stock that it cost to have the bushing made. Go figure.

That's what I thought. Was curious what it turned out to look like. Thanks for the info! Glad I'll be able to use the trans!

Well, my t86 is toast... Pulled it out today and found many teeth in the trans case. YEEHAW! Now I gotta get serious about the t85 installation. Does any one know how long the input shaft is from the F100 and the car unit? The longer pilot bushing sounds like the ticket, but I want to be sure it will work on my 223.

There is where the problem lies when mixing apples and oranges. The collar/bearing retainer for the throw out bearing on the trucks is different then the cars.

I don't think they exist. As far as I know they never used a T85 in the earlier trucks.
