OK.. Another BB update; the bike is in fantastic condition, and the current BB is actually in good shape. However, I'm realizing that I'm probably going to need a shorter spindle, and then I'll still have to mount the chainring on the inside of the crank. That is well and good, but I could also just upgrade to the Sugino 103MM BB which uses cartridge bearings.
That would allow more flexibily in the crank decision, but the roadblock I'm hitting now is that I found out there are two types of taper for the stinkin square taper cranks!
