I would be up for remaking them and helping out. But I would need one to make a mold off of. Never played the game so I am not to familiar with where it is breaking. I remade the ID4 head because of a same problem. No one has them and those who do want crazy money for it. I made the ID4 heads thinker in the main areas where it was breaking and it seems to hold up really well. I would think doing the same thing to the file cabinet would help it.
But I would need pics of where they break whats on the inside and what clearance I have.
If someone is close to Schererville, IN 46375 I might be able to meet up and check out the game and see what it all takes.
