1973 Dart Magnum Swap
Maintaining the underhood fuse box makes hooking it up fairly simple. The trans sensors will be necessary as will the OBD port, not much else needed wiring wise though. The Ram driveshaft will be too long. The 500s(42RH)/42RE/44RE have a steeper 1/2 than a 518/46 and also are more compact near the case requiring less floor mods.
