So I am trying to order new polygraphite bushings for my 1970 GTO from energysuspensionparts.com. They have very little listed for the 1970 GTO, but have tons of things listed for the 1970 Chevelle. As far as I know, all Buick, Chevy, Olds, and Pontiac A-bodies of the same year should have matching frames, and matching suspension components, correct? The only difference I am aware of is some have an oval bushing for the lower control arm and some have a round bushing. Am I mistaken? I was going to purchase new polygraphite body mounts (incl. hardware), front control arm bushings, sway bar bushings, sway bar end links, radiator isolators (big block), and rear coil spring isolators. The parts are all made by energy suspension, and correct me if I am wrong, but I don't see why the aftermarket polygraphite Chevelle bushings wouldn't be exactly the same as GTO bushings.
