You might try talking with Mark Purney at Supply 88 who is making action brackets for Young Changs. You might also want to find someone using water jet lasers to make metal parts. I will ask a guy here who has a shop with industrial grade equipment. Maybe there are hinges from Yamaha that will work but require some routing out of the lid. What happened to the other hinge ?
