Does anyone know of a remote coil small cap HEI distributor that has a .491 or .500 inch diameter distributor shaft?

I've got two distributor issues on my 383 that I'm trying to combine into one solution. I've been getting some roughness in my 383 SuperRam setup that I haven't been able to pin down, and noticed that the gray metal ring at the base of the inside of the distributor (which I think is the magnet for the magnetic pickup) has 2 cracks in it.

In addition to that, I'm chewing up the distributir gear awfully bad. The cam is a custom CompCam roller cam that supposedly was built with a distributor drive gear that would allow me to use my standard 91 TPI distributor, but I suspect they fouled that part up somehow. Consequently I was going to put on their composite distributor gear (at their recommendation), but my existing distributor has a .425" or so shaft and they don't make them that small.

Ideas/suggestions????
