Its unusual damage for a Corvette.
Usually just see those problems on severe abused drag race cars.
Kinda looks like the frame is thin from rust corrosion.
Most would say to replace the frame with a used frame.
It can be repaired yet but the only safe way is to make a custom plate about 4-5 times larger than or diameter surface area that broke away.
Entire area should be blasted clean with brand new virgin glass beads.
Then wire brushed again or use a Flap wheel in a disc angular grinder.
Mirror image exact as the undamged side cross checking over and over at least 5 times.
Use a TIG Welder for maximum strength.
Check again at least 3 times.
Weld in full and lay down perfect weld beads.
Just like Race car chassis work.
Only perfection done.
