One other thing, and the tooling would be out there for 95% of the piece, is the exhaust tips on a '70/71 Sport Fury GT. I think the only difference with the E- body tip and the C-body tip is the hanger and the inlet pipe. Possibly flipped over too.
Although they never came on the 300Hurst, lot's of folks think they did because of a promo pic that was circulated. I've said that if I had a 300Hurst, and they were available, I'd add them.
Ebody on left, C-body on right. These aren't mine, I got the pic from a post by a member that passed.
