OEM Pitman Arm Variations 1962-72

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?

I don't have an answer but would it be possible for you to post some pics (somebody will know).

N.O.S. 1962 O.E.M. original,with the part number it fits earlier than 62.

Unfortunately I didn’t take any pictures before putting the old one back on. For now I have the steering linkage loosely assembled until warmer weather. The original arm is almost straight as viewed from the top just like the picture that 62Max posted

The Proforged arm has a considerable hook or dogleg when viewed from the top but as I mentioned the relationship of the spline clocking to the end of the arm does appear the same as OEM so the effective geometry would appear to be the same. Also the Proforged arm has the part number cast into the arm so I know I have the correct arm....or at least as correct as Proforged makes it.

Original part # supercedes several times:1858017, 2275458, 2835746, 2835880 & 3004811
