I just checked out 2 sets of repro straps. An old set from the early 90's has offset bulges, although not quite as offset as your originals (fairly close, though). A set I recently purchased has very slightly offset bulges, but the bulges are not formed as well as the older repros. I still have my original straps stashed away somewhere at my parent's house in Maine. My plan is to take a trip up there this summer to get my originals and restore them. Nothing beats an original part. Plus, I remember my originals fitting way better than I could ever ger a set of repros to fit.
