Window Frame Adjustment
 

Is there a way to adjust the hinge in the convertible top that creates the window frame? Mine is slightly off and I can't find any information about this assembly.

Take a look through this article and compare the moving parts with yours.

The rods that go from the transmissions to the frame are probably the only place you should adjust it at unless you notice that something is broken.
