Upper control arms are touching the bump stops

That's what I was thinking. There was some weight removed years ago when I was still racing it. A/C, and power steering pump. Also replaced cast intake for aluminum, and removed beam behind the bumper and built brackets so I could re attach the bumper. During the rebuild I have replaced the steel hood and bumpers with fiberglass. Also got rid of the factory dash and installed aluminum race dash. Replaced the bench seat with a light weight race seat. Gutted the doors and installed lexan windows. Got a aluminum race radiator in place of the factory copper one. Have not weighed the car , but all these changed have probably added up to quite a bit of weight.
