I bought a 2004 Chevy Express 3500 this March. I live in MN and the side door has rusted to the point that a hole has been made in the bottom of the door. I was looking to replace the door but cant find any place to find a replacement door. Can I use another Vans door for a replacement or do I have to use a express door? Also does anyone know where I can get one? I have looked at dozen of websites but cant find one. Any help will be appreciated.
