I have an early 123 Ignition electronic distributor fitted to a 142S (B20). It’s the one where the adjustment is up from underneath. Does anyone know the common order part number (eg Bosch) of the replacement distributor cap? It’s not the same as any of my later ones and I suspect it’s a GB633, similar but with a female location slot on the cap.
