One quick question...anybody know where to find RPO codes for 1988
Chevy 4X4? I am trying to verify the rear end gear ratio.
Thanks

Sorry, my question was not clear. I found the codes in the glovebox.
What do they mean? Is there a decoder somewhere? Does anybody offer
the ability to get a copy of the original window sticker by using the
VIN?
