Never thought that could be what happened but we tried to use a punch and hammer to see if they would come off. The odd thing , well 2 odd things
1. The nuts on backside and the pins themselves don't look like they are a grade 8 bolt quality as the stock 5 stars look.
2. Who ever did this also drilled out the new bushings in the dampers to fit the expanded 5 star pins.
