Yep , one is dodge, one is plymouth. I don't remember which is which, but I saw that addressed here. I'm sure someone here can help out.
(Memory of what I read says dodge long, plymouth short. Grain of salt).
Edit: you could try "accurate exhaust" site.
See this thread "71 b body exhaust tip length" in the exhaust section .
I'm going to put machine tips on my 72 charger. .so which exhaust tip is correct for the 72 dodge? The shorter tip or the longer tip?
