GQ1 just means it's a non posi rear. G80 is for posi. Standard means what was standard for the year. It gets confusing sometimes.

Look on the front of the passenger side axle tube about 3 - 5 inches from the carrier. See if there is an RPO code stamped there. I'm pretty sure if there is a code, the first three letters will tell you what gear it came stock with. Let me know if you find a code and what the first three letters are. I also need to know what rear brakes you have. 11 x 2, or 11 x 2.75.
