Ok, just recently installed a rebuilt C4 on my 1967 mustang. Went to fire it up and it sounds like the bolts on the torque converter are striking on something as the engine turns. This was a conversion from a manual to an auto so lots of things to swap out. The tranny is lined up correctly and I did pull the pilot bearing, everything else seems to be running smooth except for these things striking on the revolution. I made sure to purchase the proper nuts specific to this application (from a mustang restoration store) so I know those aren't too deep.
My question is should there be a spacer of sorts behind the flexplate or something? How far should the nuts be screwed on to the torque converter? I made sure the torque converter was seated all the way in to the bell housing and took the time to make sure everything else was in place too, just can't figure out why these bolts would be smacking now.
