While having my 2000 Boxster top replaced with a newer glass window model, my upholster informed me that he found a broken cable. The top had been functioning fine so I went to the shop to see for myself. This is apparently a tension cable to keep the bottom of the top secure. Has anyone had this break? I need help finding a replacement as all of the cables listed for the top are either the motor cable or the much larger tension cable that actually goes through the top itself. I cannot find this specific piece. There are two, one for each side.
