Just fitted some bobbins today and standard M10 bolts (1.5mm pitch) fitted just right. The only problem I had, is the mounting face is recessed, so will need some washers to pad it out a cm or so.

frankpgh,
I have nothing to add on the spools, but I did get your PM and I'll give you a call today.

A word of warning - if you have the R&G cotton reels fitted to the swing arm and have a new chain or one with little wear on it, the rear wheel spindle cannot be removed as the chain adjuster block catches on the cotton reel.
