Non-standard side-exit push-in cap for Lucas 45D distributors. This cap is used when improved weather protection of the distributor is required, or confined space requires the side exit cap. Alternative part number for this cap is GDC142. To use this cap, normally the integral screws are removed from the cap, and two small notches are ground into the cap to accept the spring clips from the distributor in order to retain the cap. Use only with GRA2128 rotor.
