I have a wilderness rack, it's flat, not stepped like the SD ones.
I've also got 6 light mounts for it. 4 that clamp on the front, and two that bolt through the back. The mounts are for a DII, allow you to open the sunroofs. I just got all new rubber feet for it from garvin. I also sanded it down and repainted it. Looking to get $400 for it. Attached pic is from a website, I never mounted mine on my truck, and it's just taking up room
