We should have a sticky for newbs to post a bunch of stuff in so they can get their post count up.

Here's a very interesting database on spindles. Most 68mm bbs use the 52mm center width. I've got a 70mm bb on my Supercourse. I think I've got the 53.5mm kind in mine. You'd probably want the 55mm kind. Try searching these on Ebay.
