Here's an update on my flaccid mirror which is now firm and erect. Photos:
1. Pull the shafts skin back and take a firm grip, oo-err. There is already a hole in the housing drill another 2" along, I used a junior hacksaw blade to cut three sides (dremel if you can afford electricity), heat the plastic with a heat gun, hinge the flap open, cor blimey.
2. See that nut in there with a heavy spring under it, tighten it up.
3. With a 1/4"drive ratchet with 10mm socket fitted.
4. Heat the flap around the hinge area and push it back like so.
Then drop it on the floor and crack the glass while refitting it.
I had tried using heat to warm the housing to get it pliable enough to lift the glass out but failed so resorted to above, once fitted the service hatch can't be seen. Also, a tip I learned from scrambling and enduros a bit back, a few plastics will get light or white discolouration lines when stressed by bending/damage and a bit heat from a heat gun will bring the colour back, but don't get carried away.
