I was driving by a local GM dealership that is closing and I seen a sign out front that read EVERYTHING MUST GO. I went to the parts counter and they were selling all the parts catalogues. I was able to get a 1967 -1976 Camaro one and a 1971-1976 Vega catalogue . I paid 20 dollars for the pair.If a dealership is closing in your area and you would like a master parts book give them a try,you never know.
