The Stovebolt Site Forums The Shop Area General Truck Talk Can I swap cabs?

So Here's the story, and I am asking to make sure I can do this and everything is on the up and up.

I have two trucks, both with clear titles.
A 49 5 window, and a 50 3 window. The 50 has everything done to it that I want, which includes a 235, open rear, and 12v conversion.

The 5 window is pretty much stock, but in need of some help.

I live in MN, and my question is can I swap cabs so the wife gets her 5 window, and I don't have to do all the extra work, or is this a NO NO?

I would kinda like the 5 window too.
