I picked up an aftermarket roof rack from a buddy for $100. Figured it was a good deal as the ones I was looking at online were between $300-$500. Question I have is it came off a Tahoe and he doesnt have the mounting brackets so what are ya'll using for mounting brackets on the fiberglass roof? If it was a regular metal roof i'd have no worries about just a small metal braket and some botls just wasnt sure how that roof would like that. I can fabricate just about anything I could need and have a welder, grinders, etc... Thanks guys!

you can bolt it to the fiberglass top just fine

I drilled 10 holes in my fiberglass top to mount my roof rack. I put a dab of silicone in the holes before i put the screws in to keep it from leaking. It worked pretty good. My roof rack is off a 2000 Suburban I just cut it down to the right length.

Is the roof solid or in it hollow in the middle? Any problem with bolts crushing down into the fiberglass?

The center section is about 1/4" thick fiberglass. It's solid and the bolts wont crush it if you use washers and a reasonable torque spec

just use a washer and lock nut washer on each side.

another thing you can do is go to home depot and get some uni-strut and some all thread. Make sure you have a hack saw or a saw zaw. this will distribute the pressure over the length of the fiberglass top. you will need washer and nuts on each side.

Yup. That would work. I havent ever checked if the bolts are still tight but thats exactly how I have mine setup. I dont think it would be a good idea to put more than 200-300 lbs up there but I've had that much on my roof

I think the wellnuts would work if you were bolting it to the flat top surface of the shell, where they would only be holding the rack in place. But I wouldn't use them if you were mounting it to the sides of the top above the side windows - which is where I would do it. Thus, the sides of the shell bear the weight vertically so it could hold a lot more without bowing the top of the shell.

has any one used well nuts? A lot of OE applications just use those.



Wow that's a bad pic. With these, there would be no need for silicone.
that looks like i could work but i would like the security of knowing it cant move. Also if you have a nut on there u can either put lock tight on the threads or at least retighten the nut if it comes loose
