Hi Illa, glad to see you made it here to the intro thread.
We have a couple of Cadet
owners, looks like they're kissin' cousins to your Predom Prespol. Hopefully an owner will pop in and help with your questions.
From long time reading, I can tell you, window replacement is nearly impossible... buying new anyway. Because they're formed plexiglass. We had several members especially looking for the front window. They're available in Europe however.
Perhaps you can replace the bubble windows
with flat plexiglass or glass?
