Crashed 05 300c Parts Car

Simple swap: engine, (TB to pan) ecu, harness, and throttle pedal. Hotwire auto can reprogram your ecu for a old mopar trans...

Or you can use the 545rfe OD trans (if that's what it is maybe those are the NAG1 trans which I think is harder to use) and just have more mods to the floor/trans tunnel..
