Well all I can say is I love my '72. I think she looks fantastic. I love the 70 model as well. I think that your friend should do what ever he wants. If he is up for a challenge and wants to convert the car to look like a 70 then why not? If its not a numbers matching car anyway, and this will make him love his car more, I say he should go for it. I don't really think we are Mopar fans simply because we want to sell the damn things. ( Hell, I'm going to be buried in mine!) Feel free to change the look.
Obviously someone wanting to buy a genuine 1970 wont be interested, but someone looking for an awesome street car would love it. I'm looking forward to the progress pics!!
I love Mopars. Don't care what face they have.
