Hi From Pittsburgh

Welcome to FABO, glad to have you here.
With only a V.I.N., you can't get a fender tag or broadcast sheet made.
The original color would be B7 or B9 if it were a late build car.
At this point, you have back halved the car, so originality is sort of out the window at this point.
My advice is to build the car the way you want with the colors and stripe etc. of your choosing.
If you post the first 10 digits and numbers of your V.I.N. on here, it would give us most of the info we need to determine where the car was built, the original engine size, and roughly the build date of your car.
Have fun!
