Dont know the capacities but if you follow the merry christmas thread at the top of the forum, it'll take you to a spot where you can download the manual which will have all the info you need.
i am pretty sure that you do not have Dana axles. Your truck has AAM axles. The rear is an AAM 11.5 and the front is AAM 10.5, i think. I just fill up the diffs until it reaches the fill hole, so i am not sure about exact capacities.
