My G80 blew and I ordered a full True Trac kit from rons machining that came with new gears. Once the installer pulled my set, we realized the gears were perfectly fine and just the G80 had blown. I said screw it and installed the new set anyways so these are now for sale. We both inspected, he gave them a "perfectly fine" rating and they look good to me too. He said the pattern is fine, I had no noises coming from the axle either. $40 plus shipping from 92408. Will fit 8.5 and 8.6 10 bolt axles. Brett can vouch for Lenny (Installer) and if he says theyre good, theyre good. Pics in a few.
