I assume you are trying to repair an existing cabinet.
You could insert a square piece of wood in the bottom corners, and glue and screw them to the panels. But there's no room at the top, (internally). You might use 1/8 aluminum angle, and chisel out the panels to accomodate it, and epoxy, and screw them to the top, and side.
In reality, without doing major work...any repair would just be a band-aid.
Sorry to suggest, but the best alternative for such a heavy amp (should you really desire fixing the old cab) is to... remove all the tolex, do the reinforcements you see fit (biscuits or dowls and reglue), or even make a new cab out of pine. Then re-tolex and your back in business.
Better yet, purchase a new Cab from Mojo and save the old one should you sell the amp to someone needing to keep things original. Might cost you a few hundred bucks, but would save you a lot of time and trouble.
