So im getting ready to rebuild my th400 thats going in the sedan and ive got a few questions.

Bought the B&M Transkit, and it said not to be used with transmissions newer than 87. But now i look at the summit site and it doesnt have that disclaimer anymore and the applications go up to 90 now.

Got my trans and noticed trans mount bolts are metric, so now im thinking i may have a newer trans. Was told it came out of an older diesel mini bus, but could it be b/c its canadian built?

So what are the differences between the 64-87 and 87-? th400?
