This harness is a bone stock reproduction, it is not a chezzy knockoff..It is set up as a stock harness including headlights. if you were to purchase a mopar electronic ignition upgrade kit they are very easy to install and you will be then be able to use whichever box you like.. Basically removing your 55 year old harness and installing a new one that has all the right color wires and connectors, except it is new..
