Found a case that is just a hair wide, but the basses fit into. Will need a little extra padding at the bridge and one lower bout. Should be too hard to add. Reasonable, too. It's a Douglas HB model, $59 plus shipping. Not top of the line, but much better than a gig bag.
The funny part is a little tag in the top of the left corner. Yes, it actually says: DO NOT EAT.
