I am trying to find new upper control arm bumpers for my 69 nova that I am redbuilding. The bumpers I took off are bolted on like the bottom ones but the only ones I can find are the push in type (what gives). I know they are stock because the car has low miles (the rubber has age rot) and previous owner has not touched them. This car is an original l78, now would that make any difference?
