I kinda figured that it either isn't possible, or that there would have to be some changes to the conv hardware. If you watch the window as it goes into the down position, it MAY be possible to have a smaller piece of glass that does not fold into the top if there was more room above the glass.
I just got my 2000 boxster and I thought I'd check it out and see if anyone has been able to make this retrofit.
Thanks guys,

Oh jfmillr, I saw your post about being from around the DC area. I am up in MD, but I've had my boxster less than a week
