Missing fender tag

I'm in the middle of my psuedo-restoration 69 dart / Hemi clone. It was a 318 2 bbl, auto trans, radio delete, with A/C, and Power steering, and Power brakes.

Can't afford the Hemi, buddy gave me a great deal on a 340, 11.7 c/r, 360 swirl port heads, big cam, etc.

Plan is to have an outward apperance of being a Hemi car, but with LA engine, Manual steering, manual brakes, modern A/C

It did not have a fender tag on it when I bought her, So in the interest of looking original (Not trying to fool anyone)

1 - Would it be dishonest to fabricate a new tag? With the factory options? Like it should have; or as I modify it?

2 - How difficult would it be to do? Anyone have any blank tags?

Again I am in no way trying to pass it off as origanal.
