I dont think there are many skidloader salvage yards. I have spent a lot of time looking. They get repaired until there isnt much left. I have found a few tractor salvage yards that had a few. You might be able to find a skid steer in need of repair for parts.Depending on how much you need salvage yards arent cheap. Mike
