@Bigmike, tolerable in what way? Most pieces that you take from xterra that I know of are to shorten gears / climb higher, numerically. 4.6 ratio territory.
After ‘05? You can get lower numeric gearing but I’m totally unfamiliar with what diff is even back there. Sorry.
Here’s one of the mostly complete listings I’ve found for R200’s.

Other part is pathfinder 5th gear is 0.811 on an FS5r30a box. Probably unrelated to what you were talking about though?
Edit: Xrerra that I’m familiar with is 37:8 and 51:11. Idk if it’s even possible, but 37 gear on 12 or 13 pinion yields 3:1 territory but in my opinion that’s much too low.
