Was wondering if anyone can help me out to identify the correct application(s) for an original GM brake drum that I have. The part number 3684775 is on the drum. I have plugged this number into a search on gmpartswiki -- no results, no results on ebay. I'm not terribly savvy when it comes to part number searches on the internet, so any dependable info would be appreciated!

I am thinking that the number is more of a casting number rather then a part number, i get from some searches that say that if came off a 60's pickup (60-65) but nothing to confirm it though.

Maybe you could explain to us what exactly you're trying to do? If you're looking for some brake drums, I have a bunch of them in my scrap steel pile that are probably going to the scrap yard. If you're just trying to identify a drum to sell it, I can't help you there.

Thanks for the replies so far. To answer chevynut's question, I have a pair of 11" brake drum, hub, & backing plate assemblies that I want to sell. One of them has "GM 36?4775" on the outer rim. The 3rd digit is really hard to read, and I sure thought it was an 8, but it may be a 9. Any information about #3694775 would be appreciated!
