Distributor Drive Pinion Gear Washer, T1 & T3 Engines '61 & Up

This is the washer that installs underneath the distributor drive (pinion) gear.  Two are generally required to shim the gear up, but it's best to check clearances with a distributor in the case before the case is mated.  Too much up and down movement between the distributor and the gear can cause erratic timing.
