The 5.29 gears will not fit. You have the large rear diff, so the lowest gearing available will be 4.90s. On the Tcase gears, do you have an auto or a manual? Or in 2001, did they have AWD? Some of us can look in WINCAPS and compare gear part numbers to see which ones might fit.
I'll be away on business for the rest of the week but PM me your VIN and I'll compare numbers.
