Ya if you have access to a welder, or know someone who has one, its an easy fix.
Just take a piece of plate and weld it behind the frame where the tow hook got ripped off. (this will add support just incase the frame go t damaged by the explosion) then take a pieces of steel solid core and bend it into a loop then but weld the ends onto the frame.
Or you can do something fancy like WildGoody's D-rings there. Or you can make a bracket that you can slide a shackle shaft through and just hang a shackle on there.
