mine is around 5.5 (with very saggy leafs) but I have ford axles so it won't directly compare with the rest of it.
how much trimming do you find acceptable? If you are keeping the flares stock, then I can say that backspacing and bumpstops are key. keeping the backspacing close to stock helps keep the tires out of the flares when turning and longer bumpstop will keep them out of the flares when flexing.
what axles are you running? gears? wheels?
I have to echo John and say that regardless of the "value" or rarity, the 2.1 just makes for a bad daily driver. reliability is poor and engine parts are not available at any store. Automan brings his truck out for shows and the occasional weekend jaunt into town. and he's already had to source parts from europe. the engine shares things with some weird motorhome engine or something like that. He's the guy to see about getting parts when the time comes. full screen name: automan2164
I'm out of town at the moment, but I have everything but the windshield banners (and I'll have more of them soon as I can get back to michigan). Plus pretty soon we will have the Hornbrod tribute stickers ready to mail out.
it's far enough away (both in time and distance) that I can't say I'm positively going, but I positively want to go.
I'm still a bit hesitant to give a thumbs up to raffles because it's technically gambling and various places have laws concerning it plus it's hard to keep it completely open and on the up and up. But it might be because I've never done one before and it's all paranoia.
and if you're up for it, you can likely swap out the input gear for a 21 spline. don't quote me on that though. when it comes to Jeeps, things you never thought would swap will swap, and things that sound like they should swap, don't.
