You build what you want - how you want it and how you can afford it. A little bit of work but I don't see it as too hard of a project.

Buddy of mine is doing this very thing.
He bought a decent 1972 challenger body for MUCH less than half what a similar condition 1970 body costs and a used 1970 tail light panel to build what HE wants on HIS budget. I gave him my old tail lights and grille / head light doors from mmy old car to get him in the right direction
