In a bit of a pickle with my right hand side gas strut mount in the boot. Over time it was getting looser and looser until recently I attempted a fix using a Plusnut which did not work as the force of the strut has again ripped it away.

So now, I am wondering if I can put a plate behind the hole to strengthen it and use a standard washer and nut on the back. Question is, in the pic below, can I drill an access hole somewhere in the red circle in order to access the strut mount?
