When I replaced my dash I had another whole car.I bought a 1971 Monte Carlo for all my drivetrain,AC,and dash.I used the gauge cluster and all from the Monte.I used the Fuse box and dash harness from the Monte.Also usd the Engine Harness from the Monte.If I was gouing to put in a factory round gauge dash I would look hard for a Monte Dash Harness and fuse box.It will make life easier on you.I used the fuse box from the Monte and where it splits outside the firewall I used the engine harness from the Monte and other half for the chargeing and headlights was my original chevelle.None of the wires had ever been cut into on either of my cars.I just plugged it in and everything works like new.Even put an original style alternator on it instead of a one wire built in regulator like most people do.And everything works great.Give me a call and maybe I can explain it all a little better on the phone.Id be more than glad to help out in any way I can.502-492-1982
