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..
