I removed the remaining backing paper from each butyl pad and applied a generous amount of marine grade silicone in each factory threaded hole. I let that dry for a couple of hours and then applied the supplied butyl pads over each hole. Then I proceeded to apply some high zinc primer to any exposed metal. Got all 8 holes drilled cleanly and vacuumed up all the debris. That was not nearly enough to go all the way through. The track (front edge) above conformed better once fully tightened.ĭrilling Holes - the instructions called for a 3/16" bit with a depth (using a stop) of 3/16". I also skipped ahead a few steps and cut the ditch moulding at the rear to length as it was in the way and just flopping around. I just started each hole with the rails attached and then removed them to complete the drilling. There was a little coercion involved to get all the holes lined up, but nothing major. I used an Exacto knife to remove the sticky membrane covering each hole (6).Īfter this step I used the included button screws to attach each rail so I could start drilling the remaining 8 holes for the rivets. Once that was removed I dry fitted each track to ensure I accurately marked each pre-tapped hole. Drilling through my roof was scary, but I'm confident the materials provided along with the marine grade silicone I used will prevent any leaks.įirst step was to remove the ditch moulding just to the back clip - I marked each side as it would need to be cut and fitted later. This rack required the use of three of the factory threaded holes in the roof ditches along with 4 drilled and riveted holes (per side). This system includes the following components: I was lucky to have sold both at a reasonable price.live & learn. So after trying the fixed position door jamb clamp on style Rhino Rack Vortex 2500 Rack and then the bed mounted Yakima Overhaul HD Rack, I finally settled on the ditch mounted Rhino Rack Vortex RLT600 System due to the adjust-ability, ease of removing and the fact that I wanted my Tonneau Cover back on all the time.
