It isn't until you replace the subframe bushings that you will realize how much the body was flexing. If the front springs have been replaced with something stiffer and you like the ride height then replace the front bar with a TA 1 1/4" piece. GM used 1 1/8" after 1974 except on WS6 cars which got the thicker one. The rear bar was only 3/4". I'd source TA replacement springs all around. 70-74 was lower and stiffer. '75 up was softer due to owner compliants about stiff ride. I thought my '72 was real stiff until I was going over 70 then it seemed appropriate.
