This one says 49-53 Ford / Merc 6volt negative grd on the box. But you can wire them positive ground.

I suspect, all the Magsparks like this are the same unit. The part numbers change because of the mounting for each make of auto. It utilizes two condensers one on the dizzy and one on the coil. Different from the Olds Rocket picture above.


I'm using a YC, 4 lope with the contacts is series and one Mallory Best coil.


Going back to Charlies original question. Looking through the literature I have, the only two contact plates I see are one for 8cyl and one for 6cyl.
