Well, I went, and there is really nothing for jeeps there. A few sets of tires (32s/35s) for reasonable money, and LS dana 44 carriers at a couple of tables, but that was about it. Over 5 hours of wandering around at the swap meet, I saw:
1 single stock steel jeep wheel with tire
1 set of 4 stock jeep wheels with tires
1 early cherokee grille (black)
1 "honeycomb" grand cherokee alum. rim with tire
1 Jeepster 2-door (looked like one of the last years made - late 70s/early 80s?)
1 beautifully restored 4-door willys wagon for 40 grand.
Definately worth going for the entertainment value, but nothing for jeeps, and very little 4x4 stuff.
