Looking for that thing i just had in my hand...
Our front's are identical as far as the hard parts go (stock arms and bumpstops) he has polyurethane bushings (mine are in the mail)it was mostly in the front that I was seeing the difference. You're rig was doing wheelies, and the Green 1994 was tiptoeing through. There was a little bit of difference in the skinny pedal to account for some of that, but generally, I was pretty impressed with the Green one's level stance despite the terrain. My rig does wheelies just pulling in and out of my driveway
I had to get a run at everything that day, doing wheelies all day. The spot I got all tippy on was a lack of front traction deal, I slid off the line and into the rut where PA_JERO just walked over. The video is a very good example of not having proper gearing, I always tell everyone get the transfer case gears to go with those new tires. I think transfer case gearing is more important than a front locker or bigger tires. As you can see from the video I lack both of those things, I sold the 3.15:1 T-case and Detroit locker and have an ARB air locker and an even lower transfer case (looking like 4:1).
Even Mark's 2.72 gearset for the Montero is a worthwhile investment and plenty for 33" tires, it will make a world of difference. 3.15's were nice but 4:1 or better is really nice.
