I haven't had your problem JJ....got a fiberglass top Cobra myself....but
have noted that at the back end the lower walls are getting farther apart
with age. It's almost to the point that one of the inside bolt latches (it
only came with one side bolted but I put one on the other side too) barely
makes contact with the trailer side. I had been ignoring it since the only
solution seemed to be the one that 711 suggested and wasn't ready to deal
with that much brutality. Maybe a comealong would do it but then it might
pull in the "good" side.
