"Counter man" parts catalog

[davepl]

My for 1969 Canadian Pontiac I have a GM dealer parts book that has proven invaluable over the years... scanned it in as PDF and made it searchable. I just lucked across it at a swap meet 20 years ago.

I've looked for one for my truck (1970 GMC) but have not come across a reprint. I have the shop manual and assembly manual, which are great, but sometimes when you want to know what part you need, or if a part is different between two applications, the parts book really helps.

Anyone know if they're available anywhere, or if there's an electronic copy? Usually the cover several years, so anything that covers 1970 would be great for me!

Or if not, anyone know what its actually called? Searching for "truck parts catalog" gets a lot of wrong hits...

Thanks,
Dave
