Marlin,
Your new greasable sway bar bushings are the correct ones. The brackets on the front ones hang out on everyone's VX. I replaced mine last year and thought the same thing that you did, but when I got to Moab and saw that everyone's brackets stuck out on the bottom I felt a little better. I'll have to take a look at yours in Moab, because I was going to grind mine down too, but (from what I remember) if I ground them down enough, I would have ground into the mounting slot and it would have been open on one end and I didn't like that. Did you end up grinding both ends so that neither of the slots is open?
