Here is what I don't get......... there are LOTS of 340 Exhaust Manifolds on eBay and elsewhere that LOOK correct in shape, but none of them have any of the part numbers listed by 70chall440, yet YearOne has a reproduction set that fits 70 Challengers with a 340 and who knows what else. I don't care about the part numbers being correct, so is it possible for a RAMDOM set of 340 exhaust manifolds (from 1970, 71, 72, 73, 74) that LOOK like they have the correct curves will fit my 70 Challenger or am I dreaming and just need to YearOne?
Note: YearOne Reproduction Exhaust Manifolds for a 1970 Challenger 340 are listed as Part Number Left: 2863553 and Right: 2863549.
