I haven't done it on a cleveland, but have done it on other cars.
I used a std elec dizzy, removed the centrifical, epoxied it up, then removed the other parts of thetrigger wheel, leaving only one point, then cut the top of the shaft off, turned the top of the body down and made a plastic cap to go over it, ( the lid of a spray can can work !!) once it is in and set, it never needs adjusting !are there no efi 460's over there with crank triggers you can use their dizzy body ?
we have a 302W with coil packs, but is the wrong size for you
good luck.
