I do a conversion of OEM stovebolt distributors to the General Motors HEI electronic trigger system which eliminates the points and condenser. With a little bit of creative tinkering it's possible to adapt the later model cap and rotor to the early distributor, but it requires some machining that the average back yard hobbyist isn't able to do. You can usually find the later distributor on E bay with some careful shopping.

Here's a resistor:

The distributor part number you need is an 1112403- - - -1955-63
