HELP! Need Doors for 545C Skidder

Hey guys, I have a 2008 545C Caterpillar skidder and I need help in locating a set of doors. Both of my "Popped" opened catching the tires and bending them really bad. Caterpillar wants 2,000.00 for each door and thats just the frame. Any help would be greatly appreciated. They dont have to be perfect looking, just as long as they are straight and not bent. Also the doors off of the 525 and 535's wont work. Thanks, Chad...
