I personally wouldn't go to that extent on a car, almost any car. Granted if a trunk gutter is good I would reuse it along with any other part but I would not just move the number section over but that's me I realize it is done regularly. And yes when just the number section is moved over it is in attempt to deceive in my view.

Age old question, at what point is it no longer the original car. I have personally come to the conclusion that it is the passenger compartment/cage. Cowl, firewall, a-pillars, rockers, roof frame and rear quarter window structure area, you get my thought. Then I have to ask myself what if just one rocker needs replaced, or the cowl but the rear section is fine and then what about all the cars that were back halfed as a result of a collision and insurance repair early on. The water on that is very muddy, complete body replacement is not muddy.

I'll try to stay out from here but would like to know the opinions to my first questions.
