Hello everyone I've already posted some questions and it may be obvious I'm new at this a little background info about me I live in northern ohio and I own a 1971 oldsmobile 442 and decided I wanted to build a car so I bought this coupe and what I have already done to it is build the front assembly all but two spacers on the bottom of the shocks which were way to big to fit in also did all the aluminium and sorted everything and my next step is the rear irs if i can figure it out any help would be much appreciated!
