Are the HRpartsNstuff rear bolt on sway bars legal in Stock E? Also, is it correct that GM A-Body aftermarket rear control arms are legal if the bottom bar is NON-Adjustable where the top control arm can be adjustable? Paul from HRparts has mentioned that they were NHRA Stock E legal as long as they bolt in only. No welding. Anyone using one?
