'70 Challenger styling has been established as a better looking car than the '73s and '74s (apples to apples), except to statistically insignificant outliers. Own the car you want, and go about obtaining it with whatever means are available to you. Just fix the stuff that looks funky about the later models... you don't need to go all out and fake something.

And... can we all agree to spell that simple little word "of" correctly? Ov course not. Why would we all agree on anything?
