OK, this is a bit embarrassing.
I am very very aware of my limitations when it comes to doing work on cars/houses/gardens etc. Basically, I have always been incompetent but now I have physical issues including diabetic neuropathy and osteoporosis that make gripping and turning things by hand awkward.
However, finances are not good just now - I run 2 90s Alfa Romeos or 'money pits' as well - so I can't just drop into the garage to get things fixed.
The nearside mirror glass is rapidly losing it's backing so only has about 75% actual mirror left. Getting the glass itself is no problem but is there a simple guide to fitting it? I am a bit scared of the electrical connections, to be honest.
