[quote=Jac Mac;1156658][i][b]DUI do an upgraded version of the Duraspark [ check the DUI website ] where they add another bronze bush to the gear end of the housing....early Hi-Po & 289 distributors were done like this until the Ford Bean counters decided they could make more profit with only the one bush... You can probably get enough from ICE to upgrade the Duraspark with rev limiter etc or MSD can also work with it, question is will it all fit with regard to height, can send you up an old Duraspark body with cap if you want to try it for size..

Jac Mac,
Going to wait until the ICE dizzy returns and look at fitting a new shaft, I imagine the shaft fits down through top bearing, and the top plate is welded on so that might be limiting factor, maybe able to remanufacture with new bearing bush etc and re-weld top plate. You mention the block is 0.513" can you advise on distributor shaft size for clearance?

Ford Duraspark from Performance Distributors look real good and they do say you can use another ignition box coil, as you have suggested look at MSD, the old MSD 6420 is discontinued and they have replaced that with digital, and have a computer programmable version. I guess its handy to have programmable advance curves I don't know whether they work with the Duraspark...!
