Swapping differential gears

I have two Model 30 front axles of the same year group. One is a 3.56 and the other is a 4.10, one of the axle housings is in better condition than the other. I have the service manual explaining how to remove/intall all the gears, but I'm wondering if anyone would share their experience regarding gear swaps. If I do this, I'll take all the gears out of one housing and put them in the other. Thanks for your input.

It's not so much a labor of love as it is shear determination.

There is an article in the current (or maybe last month's) Peterson's 4Wheel & Offroad mag about doing a an r&p swap at home by yourself. You will need some special tools and a hydrulic press. - but this I'm sure you know.

One thing is, but I'm really not sure, is that certian groups of gears use different carriers, so be carefull. I think that 3.73 may mark the line between one sized carrier for higher gears (lower #s), and the lower gears. It may be that a 4.10 cannot go into the 3.56 without also swapping the carrier. Check this out with someone who actually knows what they are talking about, however.
