sorry I'm wrong didn't read categories properly. 
 Try what I did yrs ago with a Ford grill panel remove the rad and drilled a hole through a ply board [1/2-3/4 ply or 12 - 18mm]  large enough for a tow rope loop to fit through place a bar or  chisel through the loop behind the board in board to the engine feed the other end of the rope through grill and tie it off on a mates tow hitch. Chocked the wheels and pulled on the hand break on and get him to  slowly pulled the bend out. It may work then it may not as I don't know what damage has been done.. it worked on the Ford I could close and lock the bonnet after.
