Do you have any pitting in the bottom bracket spindle or races?

A good bike shop should have caged bearings. Otherwise get a bunch of loose bearings of the same size as came out, and pack them in with grease, as many as will fit. Reassemble. Total cost, a couple of bucks.

We also have a local bike co-op that has piles of old bottom bracket parts. A good bike shop might have a bin of discards that they would let you dig through.

You may also need some spindle bolts if not included.
