I replaced mine with the GP that Bill Harper did with the Global West units.
Put on some WD-40 and let it sit for about a half an hour.
Came off very easy and installed as easy. I'm also in the Chicago area, so I know what you mean about how the salt destroys everything. One thing I will mention is that the sway bar bolts should have some thread lock on them. I know it doesn't call for it, but my exp has been in the front end links, they come loose sometimes. Also, you might consider getting new mounting bolts, nuts and washers for the bar since I found mine pretty beat. It takes I belive a grade 8 bolt...anything less and it will fail.
