1970 C2500 Control Arms - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'd like to rebuild my suspension with new parts. Nobody seems to make lower control arms specifically for the 1970 C20/25 drum/drum application.

I was wondering if control arms from 73-87 will work, using ball joints for my drum brake spindles.

Thanks for any help.

As long as the arms are from a c20 as well they will work. The c10 lower arms will not accept a c20 ball joint

Thanks, I hoped that was the case. Tons of companies still make 73-87 3/4 ton control arms, I figured the only difference was the lower ball joints.
