I got a factory roof rack today! When I bought my runner last year it only came with the flat covers, not rails for a rack.
I found a factory rack at an LKQ for $25 with every single piece, including the often broken plastic end caps. It was in pretty rough shape cosmetically, with tons of chipping/peeling paint a bit of surface rust. So I went to Home Depot and bought some primer and black spray paint,along with some silicone and foam weatherstripping to seal everything for about $20. Sanded it down, primed, painted, and put it on the truck today. Didn't finish up 'til after dark, so no pictures - but I think everyone knows what these things look like.
I'm more excited than I should be about a factory rack, but I'm really not a fan of the plain, unadorned roof on these vehicles. Now I got it fixed!
