Yeah. That's what I really wanted to do originally, and have them in the backside of the bracket. The issue for me is that the material is too thin to sink a FHCS (flat head cap screw) flush. 14ga is ~0.070" thick. You cant even sink a #4 flush into it. It takes ~0.100" of material to sink a #6 which I used on a piece of wall art I made. RAM doesn't list the thread size on that link, but I know their 1" balls with female threads are either 1/4-20 or M6 thread. Those are much larger still and would protrude into the radio cavity. This would then rub on the plastic and could eventually rub into the battery material (not a good thing).
Like summerprophet and prerunner1982 I wanted a mount for the unit while in the vehicle. I am fortunate that I have CAD software on my computer at work, and a friend with a CNC laser at his shop. I chose 14ga since he runs it almost daily and could fit it in between other parts. 14ga is stout for this bracket but not thick enough to flush a bevel head in. At least not one large enough to securely handle the weight in offroad conditions. I had the first couple cut as a starting point and gave a couple to friends to also paly around with. I imagined the bracket as the starting point, with good geometry to hold the radio securely using the clip and allow for easy in and out. I kept the bottom open since I have a couple standard UV5R's and one with an extended battery.
OK, sorry for going off on a tangent. I'm still not 100% on where mine will end up in final form, but the RAM system is high on my list.
