What's the best resource for original part numbers for our trucks? I always thought that the Chassis and Body Parts Catalog 1946-72 1/2 thru 1 Ton Trucks 10-20-30 May, 1979 was the go-to source. While looking for some misc part numbers for my 70 C10 I noticed that some of them fell in the groups 10-15. It seems these groups were not included in the above mentioned book. Do any of y'all know what book includes the part numbers that were in those sections?
This is the parts book I have.
When I go to Group 10-15 I just have this page.
