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?

 

yeah just jack the rear up so both tires are off the ground and spin one tire if the other tire goes the same way its a posi

 

Nice fast response. Thank you
