Hello, hoping someone has experienced this but given the numbers for e320 cabriolet production I think my odds are low.

I have a 95 e320, just pruchased, with 50k miles. Today, over the washboard on the 405 near santa monica something shook loose in the head rail above the windshield, I had the top down and was hoping that when i put it up the mechanism would be back in place but no luck. Now it rattles over every bump. Anyone know how the headrail assembly comes apart? Any ideas?

Thanks
