A few pics of a great road trip and loading up.

I was happy to see the axles are very stout and should be respline-able.

Looks like I need to remove about 6 inches or so from the total width of the diff. This might be a good lsd option for a wagon as well, although the axles are 6 lug, which was my reason for going this way, as I want to keep stock lug configuration. As Okayfine noted earlier, Ford offers a myriad of options with their Mustang diffs, but I am thinking that the Dana 44 lsd that came on Isuzu Rodeo/Honda Passports should also accept other ring and pinions for a D44. Mine is 4.30
Waiting on rear rotors to get an accurate assembled measurement with my wheels to see exactly how much narrower the diff needs to be.
Also browsing the interwebs for diff narrowing info. Has anyone here ever drilled (or gouged) out the 3 plug welds on the pumpkin and removed the tubes that way? I like the idea of removing the tube, shortening it, and reinstalling the shortened tube. that would eliminate the attendant futzing of trying to align the tubes if the approach were to be cut and reweld the tubes.
edit-
Another path may be to have a precision sleeve machined to slip over the axle tubes, so I could cut the housing and slip the stubs into the sleeve and weld them up. I am a little worried about the sleeves not sealing properly when they would be reinstalled into the center section
