Thanks for the replies.
I'm working on it, but still no luck.
OSH doesn't carry latches (at least not on their website), Home Depot doesn't, Michael's doesn't, guitar center doesn't, Our local guitar workshop doesn't, the local shoe & luggage repair store doesn't (at least he'll do the work if I bring him the part.)
I have a band music store to check, but their not open mondays. Will try tomorrow.
home depot and lowes both have that latch.I had one latch on a Jackson case that was missing when I got it. I found the one shown in the image below at a local hardware store. It doesn't match the other two on the case, but it works. Pop riveted on with some backing washers inside.
