At some point in time my '69 220D was converted from loop-type glow plugs to pin-type plugs. Not knowing, I thought that the pin plugs were simply the ones used in the later MB diesels. After looking through the forum it is apparent that the threads used on these later plugs are much smaller than those on the old loop-type. However, my plugs have the same size threads as the old plugs and are an exact fit. There is a sticker in the engine compartment that says something like "This engine is equipped with Bosch fast glow plugs" (I think someone else on the forum reported a similar sticker). Does anyone know where to get these plugs? Were they only sold as a kit?
I think the Bosch number is 0 250 201 010 710
Thanks for any help
