Exhaust manifolds????

Will 3.8 n/a manifolds work on a SC? Do they have to be the same year or is there some other differences if any? Thanks

They will bolt up, but I'm not sure about the EGR fittings, plus, only 89, 90 5-spd and 94,95 have EGR. You'll need SC manifolds if you have a 90 Auto or 91-93, but the N/A may work for the others.
