Z4 hardtop - locking mechanism cover

[Z4paul]

I am not sure what else to call it but I am looking for the cover that would go over the gap located top front and centre where the locking mechanism is that secures the front of the hard top to the windscreen. I have no idea if these are ever surplus/folk are likely to have one they no longer need. Let me know if you can help, thanks all :thumbsup
