I am literally installing my 42" lightbar from Diode Dynamics today in a similar fashion. I chose to go through the firewall into the glove box, then through the inside door trim.
I had to trim off about 10.5/16 of an inch off the Trailrax Fairing to make it a snug fit.
My second set, these fit and look more natural then factory with a better fitment and look then the standard 6g. They can take a crunch well and are a proven solution.
I just came from a Jeep and my wind noise was significantly lowered already. But I had only owned the Bronco for a week before getting the rack and was worried my sound would go up. It did go up slightly but nothing compared to my Jeep. Adding the boxes was hardly noticeable.
So far I love...
I just got my A51 production photo as well. They included a link to a video that I could not open. Anyone know if this is a generic video or per build specific?
