Mixed up a bit of epoxy, and with the front mounts securely in place with the clamps clamped, glued the formed stainless angle iron pieces to each side of the top. When that was cured, took it all apart and added a layer of glass cloth to both sides of the stainless angles. Looks like a lot of epoxy to me, but just to be safe, I drilled and installed two button head stainless screws on each side also.
