I really got into the window regulator contributed by WyldWeasel this weekend and believe I've got a fix that can be easily installed. Needed some help with prototyping the part so met with a friend today who has a little small-part fabrication experience and will have a test part made up over the next week. Once it's fitted I'll test in the IronMan which I'm daily-driving right now. I'll post progress and any tweaking to keep everyone informed, as I aim to get it into production once the design is finalized.
There's a lot of ways the window issue can be permanently "fixed", but the real challenge for me is to develop something that almost anyone can install in their garage with basic tools and simple instructions.
