The repro stickers are nothing more than a detail item, same as TN stickers for your shocks or <u>BE</u> stickers for your brake drums. You arent swapping any numbers on a car by putting a new sticker on, just repeating the REAL VIN numbers that are already on the actual VIN tag in the dash. I'm as anti-rebody as anyone, but I sure don't consider adding one of these stickers with the same number as your dashboard VIN to be in any way "rebodying" a car.
I doubt anyone else does either.
