OBX Headers????????

If Im not mistaking those are the same ones that I posted, the both collect at the center. Would they work on a 1974 Dart Sport 318/904?

Yes they are I was just pointing out that I had just seen them too. A center dump will not work due to the steering box being right there. Unfortunately the tolerances between A-bodies vary significantly. So if a set of headers fit on one 74 Dart Sport the chance of them fitting with no mods or problems on yours would be surprising. Again it is a really tight squeeze for any header and MA Mopar didn't do us any favors with the differences in tolerances. Ive heard that Dougs, Heddman, and TTI fit the best but will still need slight massaging to fit perfectly.
