I wish you lived closer I would come over and lend you a hand.

I was really worried about that too, that is why I made that little tool. I used it and every single hole was perfect, according to Chris @ LOD even if you are a little off you can drill out the holes in the sliders and they will still have 100% Strength. I was really worried too but after the first hole drilled and tapped I gained more confidence. It was actually one of the smoothest installs I've done. Much much easier than the ARB Bumper.

Please take a trip to Orchard Supply and hardware and look at the following:
For marking the holes I took a 1/4" x 3" npt brass nipple which has a 1/2" OD and 3/8" ID (you can find them in the plumbing section). Then take a 3/8" drill bit for wood with a brad point and slip it through the nipple, It fits rather snug perfect for our uses. You can now place the nipple into the hole in the slider and tap on the drill bit with a hammer. Presto a perfectly centered mark for drilling.

 

Thanks for the info. I'm gonna try to get them put on tomorrow. (Sunday March 15)

 

Good luck!! Please make sure you have a friend, these things are heavy. Did you get the parts for the centering tool?.

 

Was unable to accomplish it this past weekend. Gonna shoot for this next weekend! Hopefully nothing comes up and prevents me from getting them on this weekend.
