I have been using the hanger-9 remote glow plug adapters. I don't have a part number for you, but they sure are slick. A spring loaded clip keeps the connector on the plug. On the external portion of the plug, it is a headphone jack, they give you an adapter to use with your glow ignitor. Very good stuff. I like the fact that you don't have a "glow plug" sticking out of your cowl.

I will try to find a part number.
