Please forgive me. I am new to solid axle american cars. I just got my 88 IROC and looked up the rpo codes. It says I have a posi rear end. Is there an external way to verify this? I don't want to take the diff cover off if i don't have too and I'd prefer not to try a burn out in front of the house. Can I tell by lifting the rear and spinning the tires?
