Ford 7.3L Power Stroke (1999-2003) :: 2001 - Swap Of Rear Axle?

I picked up an '01 F-350 standard cab and bed plow truck for parts and am preparing to swap the rear axle into my E99 F-250 SB unless someone gives me good reason to just swap the carrier. I want the LS differential. I will also do hutch/harpoon on the tank so I figure that bed removal will make both jobs easier. Once I have both beds off I can give things a visual and see what lines and cables need to be changed out as well. I believe that there is a difference in the passenger's side caliper but I am not 100% on that and I don't know what I will need to change if anything. I am hoping that my drive shaft will remain.

Thus far I have gotten to rotted bed off of the donor truck. The bolts would not come out and I had misplaced my cutoff wheel so out came the torch. In the process of blowing the heads off of the bolts I also blew some holes in the bed but didn't care, it's scrap. Fortunately I did not blow any molten steel onto the fuel tank. I was able to lift the bed far enough to reach the light plugs in the rear and disconnect them without damaging them. The large one that is still attached to the frame goes to the trailer lights and could have stayed connected. The two smaller ones with ends up feed the tail lights and license plate lights, they have to be disconnected.

The bed is shot so I just hooked chains into the rear pockets and drug it off with the front end loader. I did have to get off a couple of times and unsnag it from the frame. Oops, and to cut off the fuel tank fill and vent hoses.

The bolts are extremely rusty and wouldn't budge so I cut them off.

The organ recipient has a spray on bed liner that I had to cut through to get to the bed bolts, the heads look like new and the bolts look like they will all come out for me.

And this is what the nuts and clips look like that mount the bed to the frame.

Yep, there is plenty of rust.

Also, I found two safety cables wrapped around the bed frame and main frame mid bed that will need to be disconnected before bed removal. These are on the E99 SB only, not on the '01 standard bed.
