Mid Plate Questions

The Friends dragster has a spacer for the crank because, the mid plate is 1/4. That spacer has a shoulder to duplicate the flange so, the starter ring is registered. His starter is a Tilton, without the nose cone and it is bolted to the mid plate. This same set has been on the car since 1993. Only piece we have changed was the front plate, due to the water, or additives, eating that plate.
