Viper engine and transmission in my 1974 Dart Swinger

I think the physical bolting in is the easy part. Are you getting the engine/powertrain and body harnesses and modules? I think that's the only way it will get in and running without some serious ECM creativity with an aftermarket company. I think it would be wicked cool either way but I'd want all the factory wiring intact (even to the gages if possible) so I could re-wire the car and parts.
