Hey Ted, just have some fun with it: make one with crayons & pencil that looks like a 1st-grader did it, and put it on the dash or window at Cars & Coffee or whatever.

If you just want to have a nice run down of what the car has, get a window sticker for 40 bucks. I got one laminated to tape on the window at cars and coffee. It looks cool and isn’t going to be taken as a fraud attempt. I made up a funny dealer from Beverly Hills for it as my car is gold and from CA. I’d have to look back at who I used, but they were easy to find on Google.

Back in the 80's there was a 71 Road Runner that was in numerous shows. He displayed the build sheet with a "6" that was put in for the air grabber hood(N96). Clearly you could see it was not original. Have you looked for the other build sheets? Behind the back seat, Top of the glove box, Under the carper and sometimes in the front seat backs. My 71RR I found 3 of them but the one on the glove box was in the best shape(other than being crumpled). I can see where having a "new" build sheet or window sticker would be nice to have. But it would have to be authentic to the car. If you are selling it I would think most buyers know what to look for to spot a fraud. I don't think someone is going to take what is on a reproduced copy for fact. But there are people that will do it just to cash in. I don't see anybody reproducing what time has done to the original build sheets. So if you have one original to the car you are golden.
