NOTES:
o Special hardware for things like gas tank straps, glovebox mounting, etc are not listed.
SIZES:
I list things with the THREAD SIZE, NOT the size of the wrench, spanner, socket etc etc. For example, a 6mm Nut or Head of a Bolt, will take a 10mm socket. This is pretty standard throughout the hardware world, though both Vespa and Lambretta used odd-sized hardware from time to time, for example:
o Vespa and Lambretta used 14mm Socket Sized Wheel Rim nuts
o Lambretta used a special 9mm head bolt (its a 6mm thread) to hold the cruciform selector spider
o Vespa uses a lot of 9mm thread sized hardware, which is not normal (neither is 7mm actually) and is hard to find from suppliers.
