Spid and sales order questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My spid says I have a G86 no spin. Longhair told me that was a detroit locker. I was looking at my original sales order and it says I have G87max trac...Whats that? The spid doesn't list the G87 and the sales order doesn't list the G86.

Id like to learn a little bit more about whats going on under my truck. I get some pretty big clunking under there at times. Is there a tag or numbers on the front and rears I can take pictures of and post em here for identification? Id like to know the ratios too. The original owner told me they were 4 something but I dont remember.
