Does anyone have a dimensioned drawing or just the numbers on the height and diameter of a Vertex magneto as installed in a VW? Thanks! EDIT: Good news, I found one. Bad news, it's still not completely clear. Diameter seems clear at 3.75" but the height above the engine is still unclear for the VW Vertex (model 704000, I think). 9" seems like a good place to start. I was trying to compare with the Davis Unified Ignition (DUI), which is 8.5" high but 5.25" in diameter. If anyone can confirm the VW Vertex figures that would still be a big help.
