Ride height

I don't think it's that important as long as you have adequate travel up/ down and "it's where you want it," and within 1/8" side to side. Look in the shop manual for measurement technique

According to the 72 manual, the 4 dr is 2 1/8", 2 dr is 1 5/8" Now these are basically the same cars using the same front end parts, so why the difference?
