With a family of 4 and too many toys, I need to put a rack on my truck. Has anyone used the Yakima brackets on their fiberglass top. From looking at it there is space between the top of the window and what looks to be a support that would be about the right height for the bracket and the raingutter towers. Yakima doesn't recommend it in their fitment guide but I'm not thrilled with their solution either. I hate to put holes in my top, cuz if there's a hole it "will" leak, it's just a matter of when. Any suggestions????
