help with old raleigh frame. please.
 

So I have a couple of old raleighs and have the hardest time finding seat binder bolts for them. does anybody know what size I would need on a 74 professional lengthwise and where I can get them online? everything seems too long. also if anybody has a source for quill bolts and expanders that would be helpful too. thanks.

A '74 Raleigh Pro will use the standard 8mm diameter Campagnolo binder bolt.

If you are having a hard time finding those parts, http://loosescrews.com/ is a good place to look.
