70's Miyata w/cottered cranks -- bb threading?
Hey gurus, I am fixing up an old junker Miyata -- orange women's road bike - stem shifters, cottered cranks, heavy, appears to have the frame tubes connected just by smashing tubes together (don't know what it's called, but not pretty, typical looking lugs or anything).
I plan to jerk the cottered cranks out and replace with a square taper crankset I have in the shed. Should I expect English or Italian/French threading on that old fixed cup? I'm going to make one of Sheldon's tools for the removal and just wondered.
Thanks for any help, I'll post pictures once I can.
