With an auto tranny you should have 3.55 gears regardless of the year.
The best way to tell is to remove the cover and count the teeth on the gears.

In 4.0 vehicles with the automatic you are right, 3.55
Smaller engines, lower gears (numerically higher).

your 93 will bolt right in. If it has the same gear ratio, then you are good to go. An easy way to compare is, mark the axle shaft or pinion yoke then block the jeep (to keep it from moving) put the transfer case in neutral jack the drivers side wheel up and spin the tire exactly one full rotation (no more, no less) while you count the number of times the front drive shaft turns.
If you do this to both axles, and they turn out to be the same than you are good to go ahead with the swap.
What threads did you strip? Just curious....cause a repair may be easier than a swap.

I might be wrong on this, but I think with only one wheel lifted off the ground, using the "count turns" method you have to double (or halve) the resulting ratio (double if you turn one, halve if you turn the other, I am pretty sure you double if turning the driveshaft.) Luckily normal/available ratios only range from 3.07 to 5.38 or so for Jeep axles, so you can always tell if you did the math wrong and reverse it.
If you lift both wheels and turn the driveshaft, you just count.

Repairing threads is easier than swapping axles.
Heli-Coil thread repair kits can be purchased from some auto parts stores or ordered on the Internet.

Threads for the 36MM nut that holds the unit hub assembly to the axle shaft ?
The Junkyards are full to the fences with Cash 4 Clunkers, stop by the junkyard and pull some spare axle shafts. Make sure you get a shaft with the larger 5-297x u-joints from an ABS D30 axle or a newer Cherokee.
Changing an axle shaft is easier than swapping an axle.
