400 direction indicator switch mechanism

[Marcus]

Has anyone replaced or modified the turn indicator mechanism? My switch and wooden 'top hat' visible on the facia ledge are in perfect shape but the timer and 'click' switch hidden behind the facia and accessed from the engine compartment are worn and will not remain selected - they cancel after just a few seconds of operation.

I have in mind buying a new after market turn switch and modify it to replace the concealed timer and 'click' switch using the original shaft and switch as fitted and visible. I have really no need of the 10 second (?) timer aspect as I would actually prefer a 'positive' on on/off mechanism and I can modify various types but as there is a wealth of information out there, it is so much easier to copy someone else's efforts if they are kind enough to offer the 'new' switch makers name and part number.
