I had to drill out the front spring hanger to accept the larger bolts, also used longer shocks. I bought a longer rear rubber brake hose but my old one seems to be long enough, barely.
Was your car originally a V8 or /6 car? Sorry, I don't remember off hand. It seems some info I am finding, the /6 had the 1/2" bolt and V8 had 5/8" bolts. IDK
