Electronic distributors

Nice unit. Rick sells nice stuff. No need for HEI if you get that. It's every bit as good or better.
That particular item is just the distributer. The OP will still need either a Mopar ign module, coil and ballast resistor or HEI module and coil.
Rick does have the complete kit available.
