Here is the deal
The cladding is installed by hand at the factory. So not one cladding is going to be in the same position as the next. When Bob made the mold he made it to his truck.

With that said, that is the reason why I say you will have to start from scratch on this. Unless you want it to look like Hellen Keller installed it
