Transmission Surprise

[cjhall]

So I have been rebuilding my C4 transmission this week and today I went to put the rear extension rear seal in and it looked nothing like the one in my rebuild kit, or the one I took out.

It turns out that I have a rear extension housing from a van. I also have a bolt in yolk. My drive line a "slip" portion in it. This being my first F100, I didn't think anything of it when taking the transmission out.

Is this set up common on trucks? Is there any advantage/disadvantage to having this set up in my truck? I'll eventually build her into a hot rod truck with a built up engine. Will I want to change it then?

the dentsides had a slip yoke on the c6 transmissions. and i think the falcon i had with a c4 in it had a slip yoke also. if it fits and works why mess with it.

The bolt on yoke is common to these trucks no matter what trans they came with.My 72 C4 also has a bolt on yoke.
