If any list-members have said seat binder bolt I would like to borrow it for a few days. I will care for it like my own and insure its safe return. I have a full machine shop and can fabricate a copy. It is much easier to identify OD threads than ID threads. Plus, I can imitate its overall design. If someone would indulge me this favor I am prepared to offer my appreciation in hard currency or vintage bike parts.
Thanks,
