Go to Al Knoch's website. He has a video on how to do it yourself. I watched the video and I also watched Al's people install my 68 Convertible top, in person, at the Pomona Swap Meet. My convertible top was a factory install...May 1968, .....and it didn't really fit that well. Al's team did a masterly job. They adjusted the convertible top frame..other embellishments and the top fits just so perfectly. The top looks factory duplicate and fits perfectly.
