I'm currently dealing with these atm for my 68 GTO.

Overall quality of the weldments for uppers and lowers seems good. Ball joints don't look terrible but I'm replacing mine anyways.

The bushing for the uppers are sloppy though. They are comprised of an aluminum sleeve with a nylon insert. The sleeve should be a press fit into the arms, but mine have around .008" clearance. I'll be machining new aluminum sleeves oversize to take up the slop to the arm and reusing the nylon bushing.

Lowers don't seem to have the same issue and seem fine.

Alternatively, one could knurl the OD of the bushings and use retaining compound to secure them in place.
