Wow, now that's gonna be a cool project if you can work out all the details!! I've 'dreamed' about that kind of swap into an F150, but of course, I don't have the resources to do such a thing.... (time and money being the biggest 'cons' of the deal!)
When you get this deal going, it would be great if you could keep us all updated on it's progress! I don't recall anyone here doing such a thing, and documenting it, but you could be the first!
Best of luck to ya and I hope you can make this happen!
