123 300D Driver,

How did you switch to parallel plugs, did you use a bushing or something. The serial plugs are much larger in diameter. If I can do this, I'll do it in a heartbeat. The relay and everything is on the car still, the car was originally a parallel glow plugged engine. The engine I have now is an interim engine for use until the original is ready to go back in.

Thanks everyone for your responses,
