Convertible assembly parts

Does anyone have pictures of a 64 dart convertible(or similar build) assembly with the top down and no boot covering it?

On mine it appears there were latches on either side to hold the top down then have the boot over it, but there are just two metal arms, no actual latches.

I've searched and have never been able to find a picture of what it should look like, and never been able to find a supplier for the part(if there is one).

Any help would be appreciated since the point of a convert is to have the top down, and I really don't want to cruise with bungee cords holding the thing down haha.
