Today was interesting. My slip yoke arrived along with the cut to length driveshaft. Running 1350 ujoint at the trans and 1310/1350 at the rear pinion which is all good. Trouble arose with the th400… it’s from a truck and has a bolt on yoke which was a know item. What I didn’t realize is that there are 2 sizes of yoke and the one in the trans tail housing is a smaller diameter than the slip yoke.
In a brilliant stroke of luck… when we picked up the th400, the seller had a second th400 that he was throwing in at no extra cost. Also a truck trans but turns out the tail housing is the larger diameter… so after a bit of a hassle the slip yoke is in.
Dad saved the day… he was the one that wanted to take apart the junk trans and compare them.
