Dogface, hope I did not lead you astray. I was under the impression you were already with, or would have, and open driveline. Not sure Yukon can help there but I know they can on other stuff.
(I have went V8 and open driveline. Took out the torque tube and put in a pumpkin from a 59 into my original housing... and ordered a 3.08 from Yukon) Sorry if I caused anyone confusion.
