Thanks for the inputs on the radiator/coolant issue!
As far as side steps/rock guards are concerned. I'm going to go ahead and pick up a set of actual rock sliders when it's feasible. Also, after looking at the truck just sitting on the 31's with no rock sliders, a decent set of 33's will take that truck a long way. Granted, it's only technically best case scenario after putting them on I'll get a 1.5" extra worth of ground clearance, but these trucks sit pretty high as it is. Side by side, I match up with my buddy's Jeep with a 3" suspension lift on 33" tires right now.
Also, I found a junkyard here locally with two Gen II LS's here. I already pulled all the air conditioning knobs, seeing as I lose them all the time. Next up, a new review mirror, seeing as my wife ripped ours off trying to pull an old air freshener off. Also, one of them has an inclinometer, and mine doesn't have one. I have the oil, compass, and voltage meters on mine. I want to keep them all, and add the inclinometer, but I can't figure how to get it out of the dash, and once I do, how I'm going to fab a bracket to hold it. Any suggestions on that?
