My 1965 230SL is a Hong Kong registered car and it came with no side mirrors. I think side mirrors were an option back in those days. Another HK Pagoda that I know here also came without side mirrors.
Anyway, one of the previous owners installed a 280SL style mirror on the driver's side. I bought a right hand swan neck mirror, tried to install it but got stuck. The 280SL mirror has a larger base and in order to fit the swan neck mirror, I need to patch up a hole otherwise, it will be visible. No idea how to patch up the hole yet...and my garage hasn't any suggestions neither....
