I mostly use a German site www.bike-components.de but also www.mantel-bikeparts.nl
Mammoet is an OK bikeshop in The Hague, also Hans Struijk (say hi to my friend Rien if you go there, he's the tallest guy in the shop). Both shops are very near Hollands Spoor train station
But if you want to source '80s parts, best try the Dutch sellers on here, or ask Mario at http://www.defietsenmaker.nl/ (in English too, yay ;-) )
