I'm brand new to this forum, so I hope this is posted in the right place.
I'm building a fixie from my old 1985 Corsair (really fine machine....lol) and I'm relatively new to this bicycle stuff so I was wondering if someone could tell me what the parts are sized like on this bike.
The stuff I would like to know is Bottom Bracket size, Hub size/style, and pretty much that is it.
The reason I ask is because I am ordering new parts from China and would like to be very specific about what I need.

Any help would be greatly appreciated.
Thanks in advance,
