Prevent premature oil pump wear with the Goodson Distributor Depth Gauge
Are you working on a Big Block or Small Block Chevy with a distributor? Avoid problem wear and potential failure caused by a distributor that fits too deep. This easy-to-use gauge measures the depth of engagement allowing you to compensate to create adequate clearance. The kit comes complete with a .500" diameter adaptor shaft.
