I went by a local GM dealership today that is closing and was able to buy the 1967-1976 camaro master parts book along with the 1971-76 Vega parts book. I paid 20 dollars for the pair of them. Try out the dealerships that are closing in your area if you would like a set.
STOLE THEM!
Checked with a local dealer. Was told they don't use or have books anymore.
I got my complete Chevrolet set of 1948 - 1972 Parts for every Chevrolet and trucks with the GM Dealer stands that hold them up on the parts counter for $500 and that was very good deal for a complete set.
I have the whole parts catalog on microfiche I got off ebay 10 years ago. Caan't remember what I paid but got a new reader and all cheap.
