you poor guys, (and gals) I feel bad...the bushings, and uca bolts that came out of my 68 cuda, werent that bad, they were sorta tough to come off, but not that hard like you guys are describing...
Not all of them are such a pain. I blame the worst rusted on road salt.
My 67 vert had crap trapped in the tiny gaps between that upper arm support and the inner fender so that sheet metal was rusted through also. A saw removed the rusted sections and those upper arm bolts were much easier accessed. They still weren't comming out though. Since the remainder of the inner fenders are in good condition I am considering a bolt on rubber flap sort of a splash guard similar to whats found on most everything but the a-body.
