You will have to get someone to cut a pair for you from a junk yard. Get the parts from the deep south to avoid rust. I used to cut them for people, but I am getting older, and do not feel like doing that job any more. The yards here allow only battery tools. When you find someone to do it, get the dogleg in front of the wheel, and make the cut above the body line at the top of the side trim. If you can get the inner part of the well, you will probably need it too.
Try BUICKNUTT. He usually has some cars in his possession. He is in Calif. and his cars will probably have good quarters. Ship them by Greyhound to get the best price.
There are no wagons in the local yards right now.
