So....What is YOUR opinion on VIN swaps ?

Here you go WHAT ifing the hell out of this subject. Buy a complete new body and affix your 440 6 pak tittle to it, It's illegal period. Maybe someone here has already gone thru this process with a new body purchase? Legally it will not be tittled a 1970 V code Challenger!
Now if chrysler made those new replacement bodies and not dynacorn would it still be not be a 1970 V code challenger when assembled and titled? I mean it would be a factory chrysler body.

Again not trying to play the devils advocate, just trying to state that theres other what iffs on this subject.

Also DMVs in different states require different things and such to jump thru the hoops in each prospective state. What is concidered legal in one state is not necessarily legal in another state.

Theoretically you could use the entire rad support and trunk weatherstrip rail assy off your rotted V code challenger and transfer both to a new dynacorn body, and its still a V code challenger. The law does not state how much of the car must remain original, only that you cannot transfer that identification to another "car" a replacement " body" technically isnt a car yet, anymore than a motorcycle "frame" is a motorcycle.
