I just recieved my 0 250 210 955 Bosch Duratherm glow plug kit for my 1981 240D. The only problem Autoparts warehouse sent the wrong glowplugs. I'll keep the relay but I need to order upgrade glowplugs.
What is the part number for these> They have the 10mm dia. shaft. the ones they sent have 18mm shaft.
Thanks,
Rich

Also, how do I do this upgrade to my 1976 300D? I think it has the loop GPS. do they make the newer pencil type for the 300D?
Thanks again.
