    Have a question for you guyz...

    I want to pick up the rear mounts for a Yakima
    rack system I purchased a while back. I've
    defined what I need but how much work is it
    going to be to mount the little puppies? I'm
    assuming I can drill through the shell and
    have a large head bolt (or bolt w/washer)
    coming all the way through. Would appreciate
    any info from those who've "ben der, dun dat"?
    Anything to watch out for?

    It almost killed me but I finally gave in and drilled holes in my topper. I bought the roof mounts and dug in. Basically what i did was measure from the back of the cap and front of the top. I measured 9 inches back and nine inches from the top of the window, took a breath and drilled my holes. siliconed the hell out of it and double washered it on the inside. I've had 5 bikes up there at one time. Its held up for three years now. Good luck

    Thanx Man!

    That's kinda the way I'm thinking right now...
    Getting everything level is gonna be the worst
    (I think) as I'm getting the side loader towers.
    Appreciate the post w/the pics. Glad to hear
    I'm not the only one tentative about poking
    holes!! :-) Later!

    Mine isn't a Yakima, but attatching it was a piece of cake. I just picked a spot on the top that was the same all the way around (the window is great for this) and made sure I was the same on each corner. Then I dirlled away. Mine isn't double-washered or anything, but I have no worries that it'll tear out. The fiberglass of the top is pretty bomber. I may put reinforcing metal plates in at a later date, but considering all the silicone I used, that may be more trouble than it is worth!

    I was a little worried about drilling holes but I figured I used peanut butter to fill holes in the walls and doors of my old dorm room so caulk wouldnt be to noticable.
