Today, the strap on my 20+ year old Bobelock case broke at the place where the little metal swivel mounts on the bracket. Pics below. The case is in otherwise fine shape. Wondering if i should just Macgyver it with a couple of zip ties, or get a new strap (if such a thing can be ordered separately) or other? I don't really want to change cases right now, as the rest of it is rock solid.
