im thinking not but i want to know if the carrier(sp?) from a 3. 54 dana 80 will fit in a 4. 10 dana 80? i have the chance to get a limited slip that had 3. 54's problem is my buddy and i want to put it in a 4. 10 geared truck. my thought is that the ring gear still bolts on the carrier the same the gear is just a different outside diamiter. i do see the thought not working but am not sure. so what do ya'll think.
