Just read your post, all our worst fears came out, but possibly it won't be as bad as first impressions. Maybe take a day or two to relax and unwind, then start the complete disassembly and inspection process. Take a pad anSd list all good parts, things that can be repaired/reused and things you need to replace. Hope you find out you've got most major parts that are good and many of the others can be massaged to return to service. Know what you have before making major decisions. Dreams die hard, so don't sell yourself short, we're all pulling for you.
