I think as a stop gap repair you should add the later 31 style brace. This will help take the pressure off of the tank. Then you can clean up around the old bracket and seal it with "Seal-all" gas tank sealer or the epoxy gas tank repair kit. This will buy you some time but in the end you'll be removing the tank and doing it properly.

Hope this helps The Old Tinbasher
