I have a 90's vintage Lyte Deluxe with the form fitting case. I broke off one of the round metal feet and since a new case isn't in my budget, I need to patch it up. Does any one know what kind of plastic those cases were made of? I'm hoping it's ABS so I can solvent weld a patch over the hole and put on a new foot. I'd really like to not have to take the foam out of the inside of the case to get to the backside of the hole.
