No idea, I'll be taking it into the shop to get them to do it (likely Urbane) - I don't have the tools for BB replacement either. It's a mid-80s (I think) Centurion LeMans.
I should get rid of the FD, I only use the 42T chainring on *very* rare occasions (like climbing the Niagara Escarpment) - I'm usually singlespeeding it on 52:19. S'ok, it's been an awesome bike and abused to hell and back for a freebie.
