I think Arb makes a universal bracket for them but they don't come with brackets, just because of the variety of roof racks out there, but a lot of guys just use L brackets from Home Depot.
Brand new never used, sold my truck before it got mounted.
I'm looking for 250Obo plus shipping!

At least you somewhat know what you have with the 6.0, you could be getting yourself into another pile of problems getting something different, if you've already invested this much, and you got it running correctly, then id say keep it.
wow! very intriguing, i might just have to take you up on that!
EDIT: just got the time off from work, so count me in!! is there anywhere i need to register or anything?
