Headers for 73 Duster with 451

Only other option, is the Bill Bagshaw design. I used his in a 440 Duster I built 20 years ago, and They fit pretty good. But number 7 and 8 pipes have to exit thru the femderwells, then they curve back into the collector underneath. They use a slip fit on those 2 pipes. I know you don't want to cut a small hole in the wheel wells, but not many choices other than the TTIs. Just isn't a lot of room under there.
Thanks very much Gary, I really don't mind the TTI at all, I just read that one post said " Will not fit A body" and then I saw another post and saw on a few sites that said the 2" TTI would fit the A body. So I guess it's a good idea to call tomorrow. But getting real life experiences from the A-Body community is very valuable.
