That is going to be the topic in Restoration Corner next month at SuperBeetles.com. I have changed mine and I remember the problem that I had getting it out. I lost a lot of blood and skin doing it. If I remember correctly there is a bolt that has to come out that secures the vent window divider in place. I had the door glass out and used something the pry the opening wide enough to slide the cable through. If you contact me with an email address I've give you a copy of next months article.
