Radiator Caps

Stant (part 10623) and Balkamp (NAPA part 703-1200) make identical radiator caps that work well on the 30-31 radiators. Both have stainless steel tops, with some brass rings and a gasket underneath. It would be a good idea to put an epoxy coating on the underside to inder rusting. These are really gas caps but they fit well on the Model A radiator neck. Bob Taylor
