Thanks for info, I have the RT 1110 trans, so is the rear box what I need to swap or change the center stack of gears. My top plate has the same bolt pattern as the standard position trans. I have the service manual for the transmission that's what I keep reading and trying to reference to the local Eaton service dept.
If I could find a set of used 3.73 or 3:53 gears for my Dana s130 rear axle that weren't over 1k, I would just swap gears front and rear and put a data 70hd front ring and pinion in my super 60 axle. Other than the rear gearset that would be a fairly cheap swap and get me where I want in the rpm range doing highway speeds with a 1:1 ratio towing.
If I can find a spare case to take pic beside I will, I can get some beside a 48re trans
