Who else makes pitman arms that are 1" 48 spline or what application originally had these splines? I have a schroeder steering gear and need a pitman arm that has a bend and am not a fan of the arm that came with the gear.
I bought a straight aluminum arm from Kears Speed Shop in Ohio. If you want a steel arm you can re-work a vintage sprint car torsion arm. They had the same 1" spline. I've bought quite a few of them on eBay although I haven't seen a lot of them lately.
Stock Car Products has sway bar arms with 1x48 splines in both al and steel, which would be easy to configure the way you want.
I have an aluminum schroder arm (took it off my car) it is 14 inches long, has a 1 inch bend, or bow to it, you can have it for postage if that will help you. Dale
