Good point about 4x4 vs. t56, I totally forgot about that part. Well, it was a pipe dream anyway, I'll never have that kind of cash. I sure like rowing my own gears and a t56 would be the perfect set of 6 ratios for my truck and my purposes.
I do have my antenna off, but not smoothed over, if you want to call that shaved. My truck is ugly and hacky, and I'm happy with that. I also run higher pressure in my tires and have done some minor wiring mods to change the behavior of the lighting systems. I used to run a LOT of lights for abandoned forested back-highways near my house.
I also added some driving lights hung from the rear spring hardware as backup lights.
I'm sure I've done a dozen other minor free/cheap mods but I can't remember what they are.
