Facet reproduction of the Bosch 'offset clip' style cap usually fitted to earlier cars (1963-1974), much cheaper than the original Bosch part (our part IG012) and similar quality. This cap has a small semi-circle cut out from the edge of the cap and a small cutout to accept a small locating lug on the body of the distributor. If your distributor body has this small lug, you will need to fit this style cap regardless of the year of the car.
(Note 'offset' means the location of the clip relative to the plug lead outlet. Later style Bosch distributors have the clip equidistant between two of the lead outlets. The earlier ones have the clip locations close to the lead outlets. Please enquire in need!)
