I had the same problem with my YJ.
I couldn't mount mine ANYWHERE! Since I have the YJ Renegade, I didn't have any of the mounting options that other people had.
Instead of paying $28, not including shipping, for the tereflex mount, I had an 18 wheeler mirror mount, that I used.
I drilled 4 holes into the passenger tailight housing, took off the cover, and bolted it right up. To ground it, I went to Ace Hardware and got 2 ft. of 12 ga wire, and two half inch eyelets (sp?) perfect ground. I ran it into the cab, and grounded it where the hardtop meets the tub, took out a hardtop bolt, put the bolt through the eyelet, screwed it back down.
