Yukon's ring gear bolt for GM 12-bolt passenger car and truck applications fits GM 8.2" housings used on Buick, Olds, Pontiac and Corvette models from the mid-1950s through the 1970s, using a 3/8" x 24 thread to match original hardware. It secures the ring gear and supports correct alignment after gear or axle service. Yukon offers the small parts needed for a complete differential rebuild.
