Clutch linkage will be an issue with a rear dump manifold on a manual trans application. The reproduction manifolds are for '63-'68 cars. '69 and newer didn't have the generator boss cast in them. I used two drivers side manifolds and cut the bosses off of both. That was the cheapest way to do it at the time. Now you can buy both manifolds same price, which is less than I paid 12 years ago.
