The header under the front of the convertible top has a sheet metal skin sort of like a short section of a hard top roof skin. This header section has a couple little bolts in slotted holes for adjusting it lengthwise, square it to the windshield frame. The sheet metal has a divot area in the ends where a screw head is. That area tends to rust through.
Back in the day, owners would repeatedly adjust the hooks under the latches until that hand lever broke.
The joys of convertibles, and T-tops, and sun roofs, is offset by the wind noise and water leaks.
Good luck with it.
