All done!
Absolutely soaked and freezing, can barely type just now- had to enlist my old man to help and use a brolly to have any hope of getting anything done! Took all the clips and bolts out from the diagram, but it felt like there was still resistance from around the handle area. Rather than pull it off & risk snapping something I managed to hold the panel out enough to contort my hand in to the clip and fit it, so the panel stayed on therefore no pictures- sorry Decks!
Everything is working now, though my Dad may never offer to help me again! Hallfrauds said they can't supply 199 paint because it contains a lead additive, my local fiat only has the pens, and a dozen local autoparts stores don't carry it either, so I have a primer-grey mirror for the time being, until I can find somewhere- even ebay seems bare!
Anyway, for anyone else attempting this:
a) be prepared to spend some time on it- maybe enlist some help- it took me about 30 mins all in- including the mirror change and fit, even though it's relatively simple.
b) watch out for resistance in the panel when you are trying to remove it, I played it safe and managed to squeeze my hand in, but my Dad (bigger hands) couldn't get near it. I wouldn't like to try to get the whole panel off, some parts on the rim are glued in places, and there are a combination of bolts, clips and screws to take off.
c) you need to lift out the control panel for the windows etc to get in at one of the bolts
Have a look at the diagrams Decks put up earlier in this post and here:

they are really useful.
Good luck to anyone else doing this, hope i don't have to do it again in the near future!
If I do, I'll have to give you a call for tips rrope!!
