Just thought i would say hello. Got some information on this site and thought i would pass along any info that i acquired through trial an error. I recently fabricated and installed a light bar mount and thought i would share some pics. Its welded aluminum weighs maybe 3 lbs. I had the light brackets welded on the tide to eliminate another bracket to buy. If anyone has any questions feel free to ask.
No factory holes To install it in. Had to self tap into the gutter and seal it very well. Don't think it's pot metal. Pot metal is usually hard to weld if at all. I'm pretty sure it aluminum as it welded easily.
i ran the wire down the drivers side windshield. The wire off the light slid right in it and i sealed it in the marine grade 3M adhesive 5200. then just fed it through under the plastic piece. then the off on button through the wire hole feed through. i was rushed when i did mine and the temp was cold and it took a while to dry so it looks a little messy in some areas but it is in there good. ill add a picture of it in a bit
