This is a pic of the spring clip that came loose and which I did not find lost inside the top. The repairperson had to loosen the inside portion of the top to reconnect it.
The spring clip when attached on both ends is right in the center of the cab roof and not an easy place to attach a cloth loop around one of those curled wire connectors.
My education cost me a little over $100.00.
No help with the pulls in the fabric though
I did learn it is a quality aftermarket top based on the fact that the rear window is sewn in and not glued in.
I also learned that the Boxster uses a different stretch device. On the Boxster it does not go all the way across. Instead it is a short stretch piece that attaches between two bars with one stretch piece on each side. They stretch in the sun and have to be retightened. There was a 06 or '10 Boxster in the lot with same out of channel issue.
