I spent a few years working in a salvage yard. Hollander, the junkyard interchange bible, was our go to. Shortly before I left that job, the boss asked me to throw out a bunch of older Hollander manuals that were in a cabinet in the back room of the office. I threw them in the dumpster I drove, rather than the square green one, lol.
If it's American between 1941 and 1994, I can look it up. My books only go back from 1955 to 1994 on foreign vehicles. So if anybody here has any questions about interchange, send me a PM and I'll try to help out
