71 Dodge Dart Swinger in England

There's a thread on here somewhere where somebody stuck a GM 4-pin module in a hollowed-out Mopar electronic box. Since your 71 dart is already converted to electronic, mod the mopar box for a GM 4 pin, or find a burnt out mopar box you can gut out and mod, then you don't need the custom bracket on the distributor, or need to rewire anything under the hood, and it looks stock. You still will need the upgraded coil and a jumper wire across the ballast wires.

Both my cars were originally points ignition so I wanted them to appear somewhat like they still have points ignition. Also make sure that ignition box has a good case ground to where its bolted down. A poor ignition box ground may be giving you that stumble.
