the bodywork?

Proper self tappers will be too hard to drill out.
Grinding is a possibility with a high speed (air) die grinder.
If you can support nearby from behind with something like a heavy lump
of metal eg club hammer head, you might be able to punch it through.
One or more small holes drilled close by in the panel might aid the
punching process.

Not nice or easy which ever way you choose.
