Has anybody done this before?

Do what YOU want.....

As long as it is not obviously rediculous like a slant six with 360 badges you won't catch too much guff about it.

No matter what you do or don't do as far as modifications, you will always have someone criticizing your car, and believe me, it could be a 100 point resto with primer paint splashes and chalk inspection marks, paint dabs and factory simulated rust in all the right spots and still, some jackass will point out a flaw.
