There is a guy makes a conversion kit for your stock Mopar dizzy to accept the GM module. I bought one and never used it.. sitting on shelf in garage.

The timing lock out plates are fairly easy to get.. who is it makes' em?? FBO? Think you can gettem through Mancini.
Anyway.. I scrapped all that and went with a straight up HEI Dizzy I picked up on Ebay. Replaced the module and coil with Petronix Flamethrower 3 parts and never looked back.
