Thanks guys for the info. It makes sense what you said about the lack of safety with fiberglass doors. We'd really rather have metal ones, despite the weight issue.
We were advised by a member that someone in Taylorsville, KY, may have some doors or know of someone. We don't have facebook (don't want it either) to look him up. I don't want to put his name out there. (Don't know if that is good pc etiquette or not.) But if someone knows of doors we need them.
