Cab swap, how much work?

[texanidiot25]

This summer, I need to tackle the rust. But, the amount I have around my windshield, in my kick panels, in the cowl... rockers... is way beyond my skills, and I don't want to ghetto rig anything. My passenger a-pillar is destroyed near the roof basically, there's a rust-threw hole at the lower side of the same one, the passenger rocker has split in 2 pieces, and one is about to fall off, along with that the spot weld at the cab broke too. Driver's side is just fair, but in a years time I see it pretty bad. i have 2 leaks under the dash, through the seam sealer which has rusted the seams. My drip rail looks like hell too. Kick panel on the passenger side is rusting unerneath the vent, and the kick panels are starting to rust fro the river of water that comes through when it rains.

Needless to say, someone with no welding and body skills should not take this on right now. My best option really is to get a less rusty cab, and drive off with that. My question is, about how much labor and time does it take to swap cabs? The truck is fairly sparse on the inside. I have found a guy who has 2 good cabs for 500 each (gotta save up on them). I'm just wondering how long it typically takes to swap cabs. What's some of the tricky and difficult parts of the swap too.

Thanks.
