67-69 convertible top frame

Dear FABO!
I have a convertible top frame from (what I believe to be) a 67-9 convertible. It is in, whay i consider to be, nice condition. There is some surface rust on both ends of the header but otherwise is good.

What is this worth?
Is the 67,8,9 tops the same?
I have an interested party and am not looking to get a mint but can't seem to find any online for sale to compare.
ThanksFABO.
