I have a earlier GM box, manual, and need a pitman arm. It mounts on the front of the frame, so I think it's off a A body. Pitman arm points toward the rear. I need 1 that has the hole, where this 1 has the joint built in, and I'd like 1 that has some drop. Does anyone know what all fits this? A lot of them listed don't even have a listing of how many splines, just what they are for. Ordering some stuff so any help will be appreciated.
