Hardtop windshield frame for a vert?

On my 67, the window frame upright/post is stamped a different shape. The exterior trim recreates the smooth/rounded body shape. A good size void between the window frame and trim was foam filled. I don't know if the different shape of the post is all they did to add strength to it.
This post needed to be quite rigid on any of them. They were reinforced, overlapping in the join area. I don't know the vert post has the same join in the same location. Anyway... I'll believe they are not interchangeable until someone proves otherwise. Good luck
