What part is this?
Seriously, are you looking for the mechanism that clamps the roof to the winscreeen?




If true, my suggestion would be read though the below thread at:

While there were numerous and challenging issues that needed to be worked through, prior to successfully repairing the soft top roof, by post #15, a malfunctioning front latch assembly was diagnosed, sourced and repaired.
