I have recently been stung on e-bay, my bad, I purchased two Life Like Proto 2000 Automobile boxcars in the UP scheme yellow/white lettering and unfortunately I didn't check the contents all that well. I now find that all of the doors are missing from both kits. Is there anyone out there who knows what replacements might be appropriate. I have been in touch with Walthers but they don't have any replacement parts any longer for these kits. Any help would be appreciated.
