EARLY A body hooker header install P/N 5208 UPDATE!
Got everything mostly buttoned up. Small cutouts work, but it's tight.
I assembled both sides of the headers and threaded them thru the fenderwell cutouts BEFORE installing the motor. I put the motor in from the bottom but I think it could be done through the top. I don't think these headers can come out fully without pulling the motor though. Definitely looks better than those giant cuts Hooker recommends.
