A was luckky to buy z3m side mirrors. To make ideal paint work i had to disassemble them.
The difference between non M z3 side mirrors is that the M mirrors have solid body, and it is impossible to separate the body from base with out saperating the inner pillar from base... Sorry for the grammar, I'm from Russia, but I hope everything is clear;)))
The pillar is connected to the base by sleeve whith spring which is locked by washer from the other side. And it is almost inposible to disconect the washer and not to destroy it.
So i decided to cut it;)
So now we got separate parts. Body and base can be painted.
But how can we assemble the mirror??
I asked turner to create a thread on the sleeve and to create the nut.
And some spare parts were created;))
Next step is to assemble all parts.
Hope this trick will be useful;)
