Common bolts/nuts/washers on type 44

[Peter Golledge]

Listers,

I am going to have my local metric supply place make up a "box
of bolts" to avoid frequent trips.  The usual suspects to be
included for Calipers, struts, sundry nuts for cam covers and
the like....  

Anyone have a list of fastener sizes they have found useful?  
Anyone found the M18 bolts that hold the hubs in at a metric 
fastener supply?

I'm also looking to buy some Silicone/FlouroSilicone vacuum
tubing to replace a bunch of lines, any good sources out there?

Thanks
