Pull switch.
There was something I could do! For rallying it is required to have an electrical breaker switch that can be activated from the outside. This is usually done by installing a pull handle at the base of the windscreen driver's side or below the rear window. As I needed one some time and the hole was already there I simply enlarged it a bit to fit and installed the handle with some sealer. Body work still needs to be done but this looks much better in the meantime.
The thing is it's not attached to anything so now I am tempted to get the FIA approved breaker switch and wire it in - more work!
