Seeing how one pitman arm is listed by Proforged and others as fitting 1962 thru 72 B bodies I thought the OEM arms were all identical. Apparently not the case because the Proforged 103-10030 arm that I bought as a replacement for a ‘68 has a different dogleg than the original. It appears functionally the same as OEM because the clocking from the spline to drag link end is the same and the effective length equal but the dogleg is obviously different.

I assume the Proforged piece is an exact replacement for certain B bodies but which ones? And why the difference in dogleg, was this for clearance on certain models?
