Hello from San Diego,
I have an original radiator available. M-WO 7 64 date on top tank. It is not perfect in the fins, but not missing any also! It looks like it may still hold liquid... I can send pictures with a P.M. that includes a phone #. I am thinking with recent sales on E-slay $500.00 is pretty fair.
Mike
P.S. Shipping is extra!
