actually, the bearing cage inside the headset fell apart. it is in about eight or nine little mismatched pieces. when I removed the headset, the bearings and pieces started to fall out; slowly though, because they were covered in dirty grease. I cleaned everything off, but it looks that even if i were to put the pieces back in, it would take forever to match them back up again. Can I use any old replacement set of bearings and cage, or do I need a specific one? My bike is a Schwinn Traveler from the 80s (I think), and the headset says "Tange Seiki Co. LTD Japan" on the top nut.
I need major help quick, because this is the bike I ride to and from school and work, and I'm screwed without it.
