I found some 2" rear blocks at auto zone on the cheap, but they couldn't tell me what vehicles they were applicable on...

If its the one in the pictures then it wont work. Our trucks have a dual center pin and that pic shows a single pin. It could just be a generic picture though. You should go to the auto zone and if its a dual center pin there's a pretty good chance they will work.

 

Thanks a ton! The one at auto zone I looked at only had one pin. So i guess it's a no go! Darn it, I thought i was gonna get a cheap way out.
