Gdads51, thank you very much for taking the time to dig all of that information up. This is exactly the kind of documentation I was hoping to find, and it is extremely helpful.

I really appreciate you going through the Delco-Remy and Chevrolet parts information and providing the original starter number along with the drive, armature, and other component information. I downloaded and saved all of the pages you posted with my truck documentation so I’ll have them for future reference.

This gives me a much better understanding of what should actually be on the truck and what I need to look for as I go through the starter.

Thanks again for taking the time to research all of this and post it. I really appreciate the help.
