Does anyone have any experience repairing broken backpack buckles? There are replacements available for sewn-in buckles like this one:

Quick attach buckle

These are 1" and 3/4" buckles, though, and I have a broken 2" waist buckle. The female side is sewn in, so I can't replace it with a standard piece; it has to have a removable/split cross bar. Does such a thing exist for 2" buckles, or am I stuck with a complicated stitching job?
