GM 8.5 10 Bolt Spider Gears
**G80 Code indicates Factory Positraction, Spider gear replacement for G80 Gov Lock are not available and should not be replaced, The Gov Lock is a ticking time bomb and needs to be replaced with either an open carrier or a quality positraction**
**1999 and Up GM, Chevy Ten bolts do not have 10 bolt 8.5 rear-ends, rather they have GM 10 Bolt 8.6 There are 2 Spider gear Options for the 8.6. In 99 and early 2000 some carriers had 2 large windows, where as the 2000 and Up Carriers have one small window and one Large window**
