Attention Glassperts

[BA17]

Been doing a little work on the contender since the weather finally warmed up a little. The previous owner added these "braces" under the gunwales up toward the bow. Not sure if there was a lot of flex or if he did it because of the bow dodger that was once installed? Where the brace contacts the liner the glass is broken on both sides of each one. The glass work leaves a little to be desired. What is y'alls opinion on the best way to attach these braces to the liner? Please don't tell me this is a trapezoidal spacer situation! I never fully grasped the concept the last time it came up. Any advice is appreciated.
