I would check the pilot shaft as Luvsracing says. Same year doesn't always mean same tranny/clutch, etc.

I long ago learned the hard way......pulled a replacement tranny, cleaned and painted it, pulled the old tranny, THEN found pilot shaft was a different diameter. GRRRRRR.....The difference between a "F" and a "H" on the stick-on tranny label........ both trannys were in the SAME year of car!
Pilot shaft bushing would not interchange, and they didn't have them in stock, anyway. They would only sell a pilot shaft bushing if you bought
a new flywheel...it was getting humorous....
