Westinghouse wc 78 md

I'm looking for a bottle chute door for my new er, old toy. The hinge is still connected but the door (flappy jobbie that the bottle exits through) has been removed. Please help, it's getting cold in my house! Thanks,

Thanks for all the advice and responses. But I just found one on a wc 102 that I'm parting out. Whatdaya need?!

Later,
