I recommend do whatever it takes to stay stock Chevy parts, post want-to-buy ads in the parts section to get what you need from 71-72 model years. Unless there is actually something wrong with your A-arms they would not need replacing. Personally I would not have anything by CPP on my truck, and would not use spacers to try to make non-disc-brake-compatible wheels fit. It would be significantly easier to get some 5-lug rally wheels that just fit. Just my 2¢ and I apologize if it's not useful advice, and I'm not trying to be critical; I just have read too many OMG threads on this forum about the state of aftermarket parts and what brake and suspension systems people have found themselves dealing with and fabrication to work around problems.
