hello , my brother has a set of headers off his 69GS 400 that i can have , will they fit my 1986 regal i'm putting a 455 BBB into ?
fitment i beleive they will i used a set from a 67 and they fit with no problem you can put them in and if they dont fit you could take them to an exhaust shop and manuver the tubes around usually for not that much
