Argosy seat hanger question

Has anyone ever removed the We-no-nah Canoe - Adjustable Seat Hangers from a Royalex Argosy with vinyl gunnels?

It appears to be as simple as drilling out the 3 rivets on each side. Am I right or is there any other action that has to be taken.



you figured it out
No other surprises. Drill them and the seat will pull out.
