Extension tool 147

[StuartC]

In the Owners' Manual for changing the rear brake lights on a 147 it refers to the screwdriver and extension tool provided.  The screwdriver is in the kit which sits inside the spare wheel.  Does anyone know where I can find the extension tool?  I could not find it with the rest of the tools.

Thanks in advance,
Stuart

Update: I just don't think there is one.  See http://www.alfaowner.com/Forum/alfa-gta-and-gt/39984-brake-light-failure.html.  Standard socket set does the job - and I think using the extension tool would be harder.
