What differential is in the old dodge motorhomes

[68charger440]

My brother has an old 1972 or 73 dodge motorhome with a 360 and a 727.  I think it is a 20' or 24' motorhome.  Anyone know what rear ends were in them?  It's been sitting since he parked it 15 or 20 years ago, but everything ran perfect when he parked it, if fact the 360 motor only had about 3000 on it after a rebuild.  I was wondering if the rear end is anything that I can use in my charger since my sure grip is going out.
