Currently Dutchman Motorsports has a 9-inch differential housing assembly with axle yokes similar to the Shark Corvette.

This procedure is the way I rebuild these differentials and is meant to be used as an educational tool for the corvette hobbyist. Once the old bearings have been removed, the replacements can stay in place during the shim selection process.
