Boss Pedals Spare Parts wanted

[bass_dinger]

I am looking for some Boss Pedals spare parts - the rubber grommet that supports the thumbscrew, two M9 half-nuts, M9 thin washers (both to secure the input and output jack), 4 M3 self-tapping screws for the base plate.  A spare base plate , and "bicycle chain" connectors to attach the pedal to the pedalboard.  And, ideally, a Boss TU2 circuit diagram.

 

I can find all of the bits separately but I can't find one supplier in the UK who does the lot.

 

Can anyone advise?
