I bought one for my 68 Charger. It fits like crap- BUT: I had some kind of mystery headers from the late 1980's. So the header length to the collector was different than what I suppose a modern Hooker is, which is what the Summit exhaust is expecting. I had to rig the whole thing together using the right side collector pipe on the left, and vice versa, and it really didn't turn out well. The mufflers ended up having to be tipped at like 30% angle for everything to fit right, and it just looks bad.

However - as I said, my problem was that whatever headers I had were a different length than what the Summit kit assumed. It was probably only a few inches longer on one side, but it made it so the Summit collector pipe would not clear the frame underneath.
