Upper Control Arm Camber Bolts
I had big problems getting the UCA's out of my 69 many many years ago. I remember it took a couple evenings of work. I think I cut away most of the bushings with an air chisel and finished it off with careful use of a cutting torch. Today's tool of choice would probably be a plasma cutter. Can you borrow or rent one?
Ironically for me, I ended up replacing the complete front sub-frame anyway because mine was too rusted. I need to rebuild my 64 front end eventually and now you've dredged up all these unpleasant memories. Hadn't thought about it too much up to now. Thanks a lot! LOL
