{Chrysler 300} Distributor update

So, I went to Rock Auto just for kicks, and they had a single point "standard performance" distributor (out of stock on D14 dual point "performance" unit recommended for 'U' code 440 engine from 1970), which came with points, condenser, cap and rotor installed and ready to drop into the engine, all for $100. I ordered it and it came yesterday. I installed it in my G, and the car started right up, so I adjusted the timing a bit and took it for a test drive. There was no noise coming from inside the cap like there is on my original that has the rotor slicing its way through 3 of the plug wire studs. There was no 'skipping' in the 55-65 mph range like there was with the original, either. There was also no pinging at all, so I dialed in a bit more advance, since I bet the advance curve is less aggressive on the single point unit than on the IBS-4011 normally used with the camshaft of a G. I can totally live with this level of performance (and lack of tachometer functionality) until I can find a place that can rebuild/repair my original unit. With that being said, does anyone know someone who rebuilds/restores distributors?

I found a listing in Hemmings for a guy named Jim from Special-Interest-Autos.com who advertises all kinds of tuneup parts available for sale, and the ad also states that he does 'restorations' of distributors. His listing is under Chrysler/Mopar parts for sale, as well as under Dodge parts for sale. Apparently he is from Rockwall, TX, which is a bit over 2 hours away from my location. I've traded voice mails with Jim, but have not spoken with him 'live' yet to discuss in detail my particular distributor and his ability to find parts to refurbish it (or what the cost would be).

Any other advice/recommendations of repair folk for Autolite distributors would be appreciated.

Thanks,
