Ha! not even close. I'm a KJ newb for the most part, but the simple fact of the matter is that even at that, I've done more mechanically than most members have on them. That's not being big-headed or even arrogant. It's just plain true.
I'm not God's gift to jeep. JBA seems like he thinks he is. I just know my shtuff, and can back that up with facts. If that seems arrogant, so be it. He does too, but just comes across terribly in my opinion.
I would gladly buy from JBA, but over the internet..he looks talked up enough on his site that I just don't feel like talking to anyone there. As stated, I have his upper arms in mine, and it rides/handles like a dream even on 32" MT's.
