Removing the runners- It's EASY.
I just took mine off my 04 today. It looks good without them, but I but on a set of SmittyBilt Black Nerf Bars in its place.

They're nice, and they are a lot less expensive than the Westin set I was looking at.
When removing the runners, be prepared for some tight squeezes on the passenger side as there are hoses running down the length of the frame that get right in the way of removing bolts. The runners attach to brackets, which are in turn attached with Allen keyed screws to the frame. There are also 10mm nuts & bolts attaching it to the sheet metal along the entire length too. There's one big bolt on the front end of each runner that's gotta some out, and you're free.
I just removed the big bolt, then Allen keyed screws, and then the 10mm bolts on the drivers side. That one came right off. The passenger side I did the same, but the last two brackets by the back I had to undo from the running board, so I could push them in and wiggle them out from behind the hoses separately.
It took me about an hour or so to get them both off, and 30 minutes to put the new ones on.
Again, it looked sweet without them too. It gives the appearance of being lifted a bit more.
I wish I had taken pics now (before, during & after), but I was pressed for time. I hope I never decide to put them back on. What a friggin pain that will be.:cryin:
Hope this helps!
