I've got a set sitting here .. 1.5 inch maybe, 1.75, I'm not really sure. I can measure them later and sell them to you for $60, or you can take them without my finding the tape measure for $40.
I'm in Fullerton, PM me when is good for you to head up. I'm around tomorrow night, and then friday and sunday I think.
I had bought two different sizes so I could make sure my jeep sat level after re-doing everything. I used the 1" ones, so these are 1.5 or 1.75, I dont remember.. their out in the garage.
