Rallye Gauges

[70challengerRTA]

I have a 70 challenger with standard gauges and I bought some Rallye gauges that i want to install. My question is will the headlamp, rear defogger, wiper and interior switches from the standard gauges work in the rallye set-up, and will the light panel inter-change. I know I will will have to replace the heater control panel but I need to know what else I will have to get.
Thanks
Jeff

The head lamps , wipers will work .If the ralley set has rear defroster it will plug in. you may have to change wiper switch to match what you have existing in the car. count the clicks when you turn your existing wiper sw.Ralley wiring harness has wire for clock-wire for tach-oil pressure switch on block will have to be changed for gages. light bar has 4 lights not non ralley 3. im sure brother e body guys will be able to add to this.
