Thanks! I'll prolly get the new pins, since that's only a few bucks. But, I'd love for someone to tell me what kind of bottom bracket threading I have (or tell me what to look for), just so I know. I'd like to upgrade it at some point later on, in either case. Thanks!

PS: I just looked at this old Sekai catalog >>> http://www.yellowjersey.org/SEKAI75.JPG. I would say my bike resembles the Sekai Concourse 1500. Still don't know the BB threading though =/.
