in response to a post I made in the Thread "Phil's truck"
Greg pointed out I should start a thread on possible Axle swaps. here's some of the info I've been coming up with. I've been concentrating on newer rears because of the use of a tone ring in the housing.
3G ram rear track width is 67.4
97-04 Dakota/97-03 Durango more of a "all out racers" swap
The Dak used drum on the rear all the way to the end of production, it's a Corporate 9.25 axle. so is the Durango,97-03 , rear track on this rear is 61.5 this rear is about 6 inches narrower then the 3g Ram , don't let the 6 lug fact scare you away, if your going to go all out, your going to want to change over to 5 lug anyway, and you can get aftermarket axles for this rear in 5 lug.
05-09 Dakota rear track is 62.9 , 5x 5.5 pattern , rear Drum.
04-09 Durango rear track is 64.4 it's 3 inch difference , "not 4 I miss wrote in my Phill's truck post".
The 04-09 Durango were the 1st Durangos to have rear Disk the disk and caliper are the same part numbers as the 3g rams ,and it's a 5X5.5 bolt pattern same as the 3G Ram.
In my opinion I think this would be a great "weekend racer's" swap, it uses the same brakes as the 3G ram and it's factory set up for a link type suspension
when the Durango changed to the newer body (2011) it went to 64.1 (I wrote to Greg that it got wider, ,my bad).
Here's a pretty good link on some of the"factory" options that are out there.

Side note I had a 71 E body Dana under my 2000 dak....that didn't go over well with some E body guys hunting for Dana's
