70-71 had contoured handles , concave for Chall , convex for Cuda to match the body lines , in 72 they went to 1 flat handle for both to cut costs , I have some spare handles but they are miles from me now or I would send you one . Dales is the only one I know of with the corrct contour for the challenger . They are dark grey inside as other said , Chryslers handles are curved for the Cuda
