In doing a little digging thru a Sept 1970 Parts book (covering 1964-1970 Chevrolet passenger cars), I found very complete rear axle, trans, and engine codes for all Chevrolets (except Corvette) from 64 thru 70, and also a complete description of the data contained on the PoP's for each of the relevant years. Is this data available online anywhere? I know the Camaro data is available on CRG, but the PoP data seemed more complete and descriptive than what I recall from the CRG..
