AJvot71:
It may be something more simple and fixable than a bent frame.
There is a tension cable in the convertible top assembly. My guess is that it is too tight to let the top fully extend when closing. From your photos, it appears that it is closing about 95% of the way leaving the front of the frame too low for the windrows to fully close. Compare to pictures from my top. Also, Here's a link to a DYI set of instructions that may be helpful.
