There is no way for Inex to tell that a certain vin plate and title came with a certain chassis. You can take a vin plate and title from car to car as long as their the same. A '34 Ford Coupe is a "34 Ford Coupe, A '37 Chevy Sedan is a '37 Chevy Sedan. Our sedan and one coupe have the vin plate that rivets on, our newer coupe has the vin plate welded on. These are all the reasons they started welding them on new chassis's now.
Go buy yourself a used vin plate and title, call Lisa Will i believe and tell her you purchased a used car. You will have to ship them the paperwork. She will then send you a new title with all the numbers matching then you just rivet the plate on the chassis. It's as simple as that, they don't need to know that you bought everything seperate.
