You poor bastard. You can see the same thing in my build thread...gaping holes like that on either side. At last check there was one inner well left in north america, I got the remaining outer wells for my car. Best way to go would be to get someone in the southern rust free states with a parts car to cut a portion of the wheel well off their car for you. I suppose you could just patch it as well. Feel around underneath, there may be more holes than you think...like near the top of the shock.
edit...and I just saw that you are in leduc....which explains the rust hole.
