70 Dart, how to change regular dash to Rallye dash?
Not to be negative......but it is more likely that the original car was too far gone.....rusty, so a donor chasis was located which turned out to be a different year and had the standard dash. Is there any sign of the VIN tag being changed on the dash? Does it match the body stampings?
It is possible that Chrysler was out of rallye parts and built the car with a standard dash......
