Yes, most bombers came in a Dana 44 and Dana 60. The one I have came with a Dana 60 semi floating diff, I plan on getting a full floating diff with maybe a 4.10 or 3.90 gear ratio limited slip (posi). If you can upgrade your diff to a posi track, I advise you to do so just to improve traction when you need it as opposed to an open diff where you can get stuck on nothing (happened to me before) when towing a sled with a load.
Best of luck
