I took the time to scan in and assemble in Adobe Acrobat all 500+ pages of the 65-70 Canadian Pontiac parts catalog (actually it goes back to the 50s in some cases). If there is sufficient interest, I'll add the diagram sections.
It's all scanned in text format (PDF) so its searchable. I'd save a copy, though, as its 30M or so and running off my home machine and home cable connection
You can find it at 1969Pontiac.com
I do hope I'm not violating any copyrights (it wasn't marked as such), and I've never seen GM nor anyone else reproduce these (unlike, say, the assembly manuals), so I don't think I'm causing anyone lost revenue. But if someone has a good reason I shouldn't have this up on my site, let me know and I'll pull it down!
