65 Valiant 200 Convertible top Frame Question

Hello Everyone,

My father in law handed down his Valiant to me last October after it sat in his garage for over 30 years (not running), After 8 or so months of work, it runs, I have it registered, and started driving it a few weeks ago. With the car, he also gave me a new top, that was still in the box, and had been sitting in his attic since the early 80's....I finally took it out of the box the other day and to my amazement it looks brand new! So I would love to get it installed, but the frame needs some repair work first. The very end of the top frame (which sits on the windshield frame) is rotted on both ends. It looks like this section of the frame will unbolt from the rest, does anyone know where I could buy just that end piece? I tried google, but all the results are for the actual tops, I can't find anything for top frames....any help would be appreciated!!
