thanks again lads,
forgot to update the thread with my new modification
so while I was at the sharknose meet I found some awesome e12 manual chrome mirrors for sale on one of the stalls. These are much thinner then the e12 electrical type you get, and they only came on very basic models, anyway the electric motors in my original mirrors had died a long time ago, and the black plastic was starting to look crap and tired.
I had to drill a new hole but they fit perfectly and the triangular black thing on the inside fits back on too.
please ignore the wonky windscreen trim - that's a prime example of when you get a pattern part! I have replaced the windscreen rubber and the chrome trim with new and its sorted. The pictures are taken as it was getting dark the other day, so they do not really show how awesome the car looks with the new mirrors, it really makes the rest of the chrome pop out at you and goes nicely with my chrome door handles.
This weekend I was invited to have my e21on display inside the main dealers as they are having a launch party for the new m3 / m4, so unlike a normal person, while the england football match was on I was outside polishing my car

Cant wait to have a go in one of them new fangled powerful bmws
