Hello, I've got a '74 Dodge D-100 that the a-arm mount where the frame tab is rusting off..forward ones are fine though and it's the same story for both left and right. The castor-camber cam adjusters are fine but that part being riveted to the frame and cross member worries me since I don't know a source for such parts other than maybe calling a local frame shop and asking for that piece.. I'll likely re-bush them too.
Thanks George
