I still have the old gears... though I'm skeptical how long they'd last considering the front yoke had about 1/8" of thrust & radial play in it!
The 3.9 ratio would definitely be nice.
Fortunately the SM420 comes with a secret weapon: the 7.05 granny gear... among the lowest of grannies ever produced!
This, along with the transfer case gives it acceptable offroad ratios.
The rock crawler bros can definitely outdo my rig... however, I can out wheel a stock Tacoma!
I just updated my gallery thread in case you're interested.
