Newbie here. Helping a young friend with his '66. It's got a 302 from a '78 and it's mated to a T-5. I think we hooked up everything properly, but when we push the clutch pedal to the floor, the throwout arm hits the front of the bellhousing opening before the clutch is disengaged. The only things I can think of are that we have the wrong arm or the pivot ball is wrong. Any thoughts? TIA Cheers, Dave
