Don't buy new hubs. Won't look right on an old Basso, even if the spacing issue could be solved.

I seem to remember from an earlier thread that you have Campy parts, Athena no? Shop on Ebay for the appropriate vintage Campagnolo hubset, 32 or 36 hole, correct spacing, preferably British freewheel thread, then repack the bearings and take it to the LBS together with Sun CR18 rims, if the frame takes 700.

Save your old wheels, even with crappy hubs. Will come in handy someday I promise you.
