HEADERS
Have the 2" Tti on my 72 Duster with a 440. Really wanted the 1 7/8 but Tti says they don't fit.
Mine fet well enough,though they hit the pass fender and the pass side torsion bar( aftermarket bigger bars). Not an issue just an annoying rattle. I will clearance them when I replace the 440.
Mine was a /6 car that was converted before I bought it. I am not 100% sure the engine is located properly.
