Ok I am in need of advice... I just got my hands on a late 80's-ish frame + threaded fork that is in good condition but needs to be stripped and painted. It came with the original headset and BB intacted in good condition. If I'm gonna pull it apart to paint it properly should I be trying to keep the original BB and headset to be repacked or should I just replace them with modern stuff? How concerned do I need to be about threading and all that fun stuff?
Also - any suggestions on where I should be hunting for parts for the build?
