What do you want to do with it? I have one about which I've just faced up to the fact that it's unsuitable for carrying the weight of my Jeep (overloaded tires--too many blowouts). I've gone through one wheel/tire upgrade when I changed from Samurai to Jeep, but now I'll need to go to forged wheels and Load Range G tires if I want to use it--that's pretty big bucks, and still doesn't address any axle or frame issues.
The lesson learned is you need to evaluate the payload capacity pretty critically.
Other than that, I'd be happy to address any specific questions you have.
