dgrinnan Posted August 28, 2022 Report Share Posted August 28, 2022 I have new bedsides. I also bought tail lights and brackets from DCM. It appears the brackets are supposed to mount to the bed pockets. There are no pre-drilled holes in the bed pocket. I am trying to figure out the best way to mount them. I am clearly going to have to drill holes but what fasteners are you using? I can go for just a bold and nut but it will be difficult to hold a nut on the inside of the bed pocket while I start and tighten a bolt. I considered riviet nuts but so far the ones I have found are smaller. 1/4 20. Not large enought. I probably need a 7/16 bolt.

Jerry Roberts Posted August 28, 2022 Report Share Posted August 28, 2022 For some reason I can't see your photo . My original bed pockets have one threaded hole from the factory . the other mounting hole is drilled straight through . Both bolts are 5/16 inch diameter . My photo is looking down from above on the passenger side . The black fasteners are for the tail light bracket . Quote Link to comment Share on other sites More sharing options...

dgrinnan Posted August 28, 2022 Author Report Share Posted August 28, 2022 Did you mount them yourself? How did you hold the nut on the backside while starting and tightening the nut? It is up inside the bed rail pocket. Quote Link to comment Share on other sites More sharing options...
Jerry Roberts Posted August 28, 2022 Report Share Posted August 28, 2022 Yes I put these brackets on myself . As far as holding the nut on the inside of the stake pocket , The nut was already fastened inside of the pocket and I couldn't see how the nut was held . I could only see that the nut had been in there a very long time and I ran a tap through it to clean out any grime , paint , and rust . The nut didn't spin free . For your application I suggest just running two bolts through the stake pocket . Quote Link to comment Share on other sites More sharing options...

dgrinnan Posted August 30, 2022 Author Report Share Posted August 30, 2022 I think I have the solution. First of all, a lot of parts/pieces were missing from my truck when I got it. I had no old parts as reference. I am trying to put things together and it is a real puzzle figuring how some of this stuff was orginially put together. I still need to confirm with DCM but they sell a "Rear cross member "L" bracket". I beleive it bolts to the rea bed crossmember and the L inserts into the botton of the stake pockets to give the bedside stability so it does not spread at the top when you open the tailgate. It appears to have pre drilled/tapped holes that I am hoping are designed to receive the tail light brackets. I will post an update once I have this assembled in case anyone else has the same problem. 1 Quote Link to comment Share on other sites More sharing options...
