BC, When swapping to 4.10 ratio, '01 till 9/'03 diffs should be plug and play. You only have axel issues when you get a facelift 4.10 diff. Double check part numbers on the axels, as I haven't compared the 4.6/4.8 diffs and axles. You may have beefed up parts that I haven't accounted for. A quick cross check on real oem should have you sorted. I'm just going off memory when I did my conversion over a year ago. Haven't had a single issue. I'd love to hear how your 4.6 does on the 4.10's. If 3.91's aren't enough, the 4.10's will liven things up for sure.
