'70 chevelle upper control arm shaft

[k92]

Rick, My blue ls-6 has the nut style control arm shaft.A local guy who I htink you know{ restored a '69 hugger orange 350hp Chevelle} just bought a really original '70 L34 convertible car which also has the nut style cross shaft.His also still has the original ball joints so I dont think a lot of work was done to it. His car as well as my blue ls-6 are both January cars.My green ls-6 is a June car and has the bolt stlye shaft.
