Hi Kees, I acquired a 1986
Bigfoot B17 a few years ago and was looking to do some repairs on the
windows as well and I emailed the company which manufactured the
windows for
Bigfoot and they said they do have replacement parts available. They actually are located in B.C. which is lucky for you. I live in California and after talking to their rep I decided not to proceed because of the cost of shipping, but they were very helpful in answering my questions. Here's the info:

Let me know how it goes. If you do get parts I'm interested in how the install went. Thanks.....Dave
