I'm looking at a nicely restored Plum Crazy 70 Challenger 440 Six Pack Automatic. It looks like a strong #2 car. However, the engine and transmission do not match. The engine is date code correct. It is an original V code car and is restored exactly as the fender tag indicates it was originally built. The fender tag, cowl, radiator support, door jam sticker all match. Can you help put a value on it? Thank you.
