Thanks GeorgeandKira.
My difficulty is that I have to replace the whole unit. Most secondhand mirrors have a model number that is different to the one for my car, but look like they are the correct shape.
It's diffiicult for me to know if they would fit unless I purchase and try the fit. Obviously I don't want the hassle of buying and having to return (at my cost!) each time.
Any ideas about how to cross reference compatibility with other mirrors? This way I would be able to choose which one to purchase and know it would be ok.
I reckon I can fiddle the electrics to work even if there are different pins on the connectors.
