Dodge Helical Posi in GM aam axle?

I have a 2001 2wd duramax with a wore out gov lock and was told i could swap in a dodge helical style posi. Ive searched and cant find much. Is this a direct swap? I have a rear axle out of a 2004 cummins with the posi,

what diff.... not like you're going to put a 9.25 aam in a 8.5 amm or 8.8 aam, you might possibly get a 10.5 gm aam to a dodge 10.5 aam.

yes the true trac diff out of the dodge 1150 AAM will fit in the GM 1150 AAm
