On my TFC savenger his shoulder/panel join-rivet-thing has loosened. The bumps should be in a cross lined up with the cross design on the in side. (That grey ring with the tabs is fine, ignore that) My first thought like very one else is; super glue. But this is going to be under some torque and I've never found super glue to be as strong as people think it is. This is on the inside so it don't need to look nice Any ideas how to tighten that up? .?
