It looks to me like the bolt anchor mounts extend down into the pylon, but nowhere near as far as they could.
A sound fix would be to switch to longer bolts which go all the way through the existing anchors, and into epoxy/glass-flox threads potted in between the pylon walls. This may require tapping through the bolt anchords, dunno. If the bolt extends down below the point where the pylon flares out at the bottom, then the bolt will be mechanically trapped, so you're not relying on the epoxy's peel strength. Potting longer bolts should be straightforward even if the platform plate is still intact. Just use a syringe to inject epoxy/flox splooge through the bolt holes. Or maybe through the pylong access hole? Then screw in the well-waxed bolts. BTW, the best way to prepare the CF surface for bonding is to "wet sand" it with wet epoxy.
