2.4 gears and down have a different sure grip and carrier. The 2.7's and up are all the same. Then in the late 1990's they changed ring gear styles and carrier I believe. Different ammount of bolts maybe. Cant remember exactly but just be aware of this when looking for gears and sure grips. So for example a Dakota up to the point they changed the guts inside the 8 1/4's could use rear gears out of any 8 1/4 Mopar they made up to that point. So JY cars should a good place to find a set of 2.94's if thats what you want you gas miser Dave.
