They are, but when i was camping and living out of the back, i had taken the interior bed walls out to gain more space, now i want to put some back in, but aluminum will save me some weight, not risk rusting, and hopefully look cool. There are tabs welded on to the bed box interior with threaded inserts that the interior bed walls screw into. While trying to pull em, over half the bolts snapped off in the inserts, so i either have to extract them or repace them. I finally got my new LED blinker setup. Both the bumper lights and corner lights are hooked to the turn signal and are LED with a resistor in parallel to prevent the hyper blink. The DRL switches on the Halos. I also used some of the high powered LEDs that I got for the turn signals in all of the gauge clusters, and really dig the amber vibe. Volt meter is in, just waiting for the t10 bulbs for the lower dash lights. And new tail lights as well.... still have to find why reverse lights don't work.
