Question on Boxster Convertible Glass Window

To Wayne Dempsey regarding Project 70 in 101 Projects Book. Replacing Boxter Top. Wayne Dempsey talks about a new technique he has been working on that would make the rear Boxter soft top plastic window replacement easier. I'm thinking a replacement plastic or glass window replacement that does not require the top removal. Zip in window or glue in window without top removal? Any news on this exciting concept. There must be a way. My top is perfect but the plastic window is cracked on both sides and turning yellow. There may a hand held sewing machine that could stitch in new plastic with the top in place. Maybe a smaller glass window that will glue into the space with the old plastic cut out. Any feedback from Wayne would be nice.

I was working on this for a while, but I couldn't come up with a solution that both worked well, and looked good too. The best solution I found was to replace the roof with one with a smaller glass window - they make them specifically for the early cars. Hope this helps

Here is a slightly different angle on replacing flexible vinyl clear plastic windows: consider using "marine grade" vinyl instead of the usual material . Why? Because although the regular material is cheap , in Los Angeles it lasts no more than 2 years outside before it yellows & then becomes brittle. This is because it contains inadequate u.v. inhibitors.This marine grade should last at least twice as long but can be hard to find at auto upholstery shops. The Trade cost of marine grade is about $40/yd(54" wide) compared to $29 for cheap clear vinyl that is often used for windows in soft tops.. It is virtually impossible to tell the difference by just looking at it so best to buy it from a reputable supplier. Locally I use Keystone -PWCC4054111"Crystal Clear" but any equivalent is fine. NAFYYY. It is 40 ga .The incremental cost factored in to the entire cost of the job is trivial considering the benefit in longevity IMHO.Whatever you use I suggest you are vigilant in verifying that the marine grade is what they actually stitch into your top! FYI the trade cost to do the stitching is the same for either grade of clear vinyl.
I hope this is helpful.
