[EF4236]

I have a Shell Valley kit with tubular front arms. My lower ball has worn out to the point of seize. I called SV for an
American made replacement part #, was told they have no idea what the joints were made for only an overseas part #. In the CC search menu there was hope but no help, part #'s given don't match anything.
I have 3300 miles and the joints are gone, also the A-Arm bushings are gone. I ordered American parts for those.

Has anyone replaced the screw in style of joints? #'s please.
