technically the crank drives both the oil pump and dizzy. The LD uses a 'short' version of the oil pump drive. There is no dizzy to drive on the diesel. I ran the LD one in my car when I had SDS on it. I believe it was 'cut off' like an inch or two above the drive gear.
I tried to google a pic really quick but couldnt find it.
