If the lower corners of the convertible top lift away from the rubber strip behind the rear window, your top is not installed correctly or the cable has torn through the pocket that holds the cable along the convertible top edges. Here's how to correct the problem if it is an installation issue:
1. The side cable goes through a grommet at the rear of the convertible top canvas. (cheap tops don't have the grommet)
2. The cable should then go through a hole in the small tab that is tucked inside the passenger compartment see photo, then through the anchor point that holds the cable tension.
3. If the cable does not run through the hole in the metal tab, it will pull away from the window. This photo shows
how tight the top is pulled against the window when the cable is run properly. In this photo, the top isn't even secured at the windshield and the top is pulled tight against the glass.
I have seen cars that the tab was bent under or the cable was not properly routed through it.
Regarding the leading edge of the convertible top flipping up like a bad hairdoo, that can also be corrected. The top must be removed from the header bow, repositioned and glued back in place with contact cement. If glued properly when installed the top won't pull backwards causing the curled up leading edge. It will make the top slightly tighter, but it will stretch out and fit right with time and warmth.
