I did. I had fun going through them last night. They came from a shop that recently closed down. They cover GM/Ford/Chrysler from 67-96.  There are parts books, time guides, wiring/vacuum diagram books, air conditioning, tune-up specs, performance specs, etc....  So far the only usable book for me personally is the Muncie transmissions manual from 1970, EVERYTHING is there with great detail and diagrams. These books cover a long list of models from the big 3. They probably arent for the hobbyist, but great for someone who isnt sure which type of car they will be working on next. There are a few for 88-93 trucks, and a set for imports. I havent fully looked through them and  I didnt pay much, but I'm glad I went. I anyone wants info from them, or the manuals themselves, just ask. I'll post a list later.
