I think comparing cars and watches is a good way to look at it. Years ago while in high school a friend bought a `67 Mustang. Within hours he changed the Ford 4bbl carb to a Holley double pumper. Of course the warranty was void, but it was never going back to Ford anyway. The thing is, it was still a genuine Mustang. Still a genuine Ford. It was never a "fake ass" at all. Today you can buy all the parts, body, interior, everything, to build a 1960s Corvette on a Chevy S10 pickup truck frame. Is it s genuine Corvette? Even using some genuine Corvette parts is it a real Corvette? Nope. It is just as my 6542 is, a replica. But if you buy a genuine 1960 Corvette frame, buy a genuine 1960 Corvette motor, interior and the rest, it is a genuine 1960 Corvette. And it is worth top dollar as a restored car. If the motor numbers do not match the original, but is still a Chevy engine, it is worth less but it is still a genuine 1960 Corvette, not a "fake ass" and worth only slightly less than the numbers matching car. freddy's watch is not a "fake ass" either. It is a genuine Rolex 6542 with a replacement insert and repainted dial. Just as stated from the start.
