Need an Expert on Windshield Moulding

I need to know what was used for the bottom windshield chrome moulding on a 1969 Barracuda Convertible. I have been told it was a chrome covered plastic that fit in the weather seal grove. I have also been told it was a piece of chrome that was mounted with clips. I have never got a straight answer. Presently I have a chrome plastic piece that fits in the grove that I think comes from a Chev truck. It is better than nothing.
I do have a proper piece of chrome from a hard top but cannot figure out how it would get mounted in the weather seal. Can anyone help?

Thanks Greg
