[Roadsters] Sun-visor/rear-view mirror screws

[D Riedel]

Well... after 2 days soak, reapplication of penetrant and heat, 5 of 8
screws came out of the visor/rear-view/roof-clamp apparatus.  On the
remaining 3, I twisted the heads off.  Damn.  Luckily, 3 of the 4 in
the centre came out, so could I throw the rear-view mirror back on
temporarily.  Any nifty tricks for solving my new problem of broken
screw extraction?
