The jackshaft was the problem with this guy. Another is the trans mount is different from the manual to auto. Mr Pants had problems with engine roll in reverse, he finally got it fixed last I remember. I met Mr pants a couple times, good guy. He's not been around in a while. Also, look under the dash where the clutch would go, it might change your mind.There was a kid with Something ,something American in his name.
He was in Oklahoma city and did it to a genII vulcan.
