MSD help pls!

Was it an ebay MSD box? I saw a photo of a Chinese knock-off that had an almost empty box with just a GM HEI module inside. A cheap fake, though even that should spark off a Mopar electronic distributor if the pickup works and has the correct gap. Try removing the distributor and spinning by hand. Look real close at the "double bullet" connector. Not all are identical and compatible. Are both yours factory ones that were on your car?
