Hey Peter,
i have the side louvers. But they are in bad shape. They have several cracks and one part is off, but i still have it. I was too lazy repairing them. I would give u these for free if you're interested. I will only charge the shipping. I was lucky to find a pair of new ones. They were 150$ +around 50$ shipping & customs, in a small store in Texas. Don't know if they still sell them. I could find it out if you want.
I will send pictures as soon as i get home.
Mike
