9.25 dakota r/t rear end swap on my e-bodie barracuda INFOS !!

I'd like to know how this plays out.

I've got an extra 9.25 3.92:1 SG 6 lug laying around.

From a 2000 Dak R/T.

I measured it and it's actually wider than the 9.25 that's under my 1980 D150!!!

Right there is a 5 lug on 4.5 shaft that's close enough in length, but.....

didn't the spline count change?
