The EFI dissies have no provision for vacuum or mechanical advance, the parts are simply not suitable.
At work I sell a brand new Blue/Black V8 distributor with a genuine Bosch module on board. I'll check on the price tomorrow.
I've sold quite a few over the last few years to the trade & have never had any performance or warranty issues with them.
Rebuilding 30+ year old distributors is not currently viable.
