@sshevela These CBI rock light brackets have an estimated 2-week lead time per the sale order that I just got via e-mail from CBI. They asked if I had a problem with the order to contact them, so I kindly asked for a refund. I honestly thought these were bolt-on until you made me realize these were Prinsu roof rack brackets that will require some modification.
While I could have drilled a hole and experiment, I decided to abort the mission. Just letting you know that I'm leaving you dry and high! Again, sorry for leading you astray, but keep us posted if you proceed and figure out a way to make those Prinsu rock light brackets work.
When I first saw the drawing of the brackets, I thought the big hole was the hole to hold the running board bolt and the little holes to hold the rock light. Upon a sober inspection of the drawing, I realized I had my holes mixed up!
