49 cab on 51 frame

[andreas_kc]

My 51 3-window cab is in fairly poor condition and have a family member a few hours away giving me a 49 5-window cab that is pretty nice but missing doors.

So thought is to use the 49 with the 51 doors and put it on the 51 frame.

Is this a pretty straightforward swap? I think the rear mount for the cab might be different but guessing that is solvable.. anything else?

If it is too much effort, I'll buy enough sheet metal to fix my current cab, just need a bunch of sheet metal.
