I'm curious if there is any difference in drive line length between 10 and 12 bolt rearends? I guess what my question really is does my driveline need to be lengthened or shortened if I go from a 12bolt to 10bolt and vise versa...

I'm building my truck to cruise on the interstate, and I've located a rearend that's a 10bolt with 2.73's. I don't want to go through the hassle or expense of setting up a rearend with different gears just to find out its not suited for what I want and then have to redo everything. Swapping rearends is far easier and cost effective than changing gears several times...
