Help needed body repair

[Rich h]

Hi what’s the best way to repair this? I can’t  put anything behind it as there it a bracket that sits flush

maybe a scrap piece of glued or taped lexan could give you enough backing?

If you have an old parts tree, melt it with acetone in a glass jar, shake well. Back the hole with some tape from behind and the side. Position the body so the part to fill is on a horizontal plane. Use a syringe to fill it with the molten plastic from the parts tree. Do it in little steps, don’t try to fix it in one go.

Super glue a washer in there of the appropriate size for screw and fill with car body filler or *milliput.*spelling? 

If a screw does mount to something through that hole, it will need strengthening of some kind.
