Very common problem on the Convertible Mustang. What happens is the fabric fatigues where the top bends right at the window. Repeated opening/closes flexes the fabric at the same spot over and over. A tiny pin hole is the results.
I personnally had this same issue. Tried multiple times to patch it. My basic problem was that the patch had to endure the same bending forces as the original top. However, I was never able to get good enough access to apply a proper fix.
I figured if the top had to come off for the repair, might as well replace it.
A new rear wind screen is not really all the $$. It's the labor to remove and install.
The general vibe I got was that the job was difficult and required skills much like an upholstery installer. Not one of my strong suits.
In the end I had a professional install a new rear wind screen. The other change I made was to pick and choose when I opened the top. I figured there are only so many lifes in the top and each use takes one away.
