I will have to either drill them out or make a new boss.

Often it's easier to lay out three new holes on the same pitch circle as the existing ones, and just drill and tap them. 120� spacing is usual, but check this on your boss. Rover use US UNC/UNF threads on these bits.

Less mucking about than getting busted bolts out!
