okay, i'm doing my trans swap right now and running into an issue. when i was at astro swapping the trans it looked like the 4 cyl input shaft was smaller than the V8 input shaft. i got the new trans up into the bell housing and its not going into place it gets about a 3/8 of an inch away from the bell housing and jams doesn't go any further. also looks like the bolt patterns are off by 1/8-3/16 of an inch. am i just being a freakin moron or are the 4 cyl bell housings smaller than the V8 bell housings?
