In addition to the old harness in the car, I have a new harness sitting in the original package that expired before I managed to use it. For RJS, it ends up being about $100 to have them re-certify it by the time shipping both ways is factored in. However, I'm going to change from bolt-in to wrap-around shoulder straps and this requires buying a new harness anyway.
