Well.....I've got one superslider on. Turns out it mounts to the sills and replaces the little body tabs that hold the plastic rocker piece on. I just put the 5 small bolts through there, while using about 20-30 muscle groups I never knew I had. Then, with the help of my jack, I was able to line up the main mounting brackets on the framerails. Bored the holes one at a time (a 5/16 metal drill bit on a high speed drill works great) and used the big bolts. It looks fantabulous!
I'm in love with 'em. Now, Ill do the other one tomorrow (in between rain showers). Then, I'll be sure to post some pics!! BTW, it is very tricky to do this alone, but it is possible. I wouldn't have been able to do it if I didn't already have the suspension and body lift, though. I would definitely recommend having an assistant and a jack. The actual weight of the sliders is 42 lbs. each, including hardware, for those who would like to know. Later.....
