http://gmpartswiki.comGM Parts Wiki is page by page viewable online. You can't download the whole book from his site. It's hosted with free access by Ian Harding. My scans of the 1973-1991 CK RV parts catalogs are searchable PDF files weighing in at 80-100 meg for each catalog set. The site is organized by printing date, not coverage dates. This list should allow you to find which CK RV catalog you need to search.
