those holes are very typical in v8 twin/multiplate applications, since they typically use a 5.5" or 4.5" button clutch with a flexplate, which would look like that. Either that's not a 7.25 clutch like the ptt/qm or that render is showing something a bit different, because I can tell you for a fact, there isn't that much flywheel around the outside of the clutch on a DSM when you use a 7.25".
