32 cabriolet door windows

[my4dv8]

Hi , on our 32 cabriolet the previous owner said the door windows rattled when up. His fix was a “U” shaped piece of wood on the B pillar which requires the window to be down when opening or closing the door ,not ideal . Is there supposed to be rubber seals in the door top ? Or some sort of seal on the A or B pillar to steady the windows. Any pictures or input would be great.
