i have a fising seat mounted on a swivl-eze lock n pin pedestal, with about a 24" pin type extension...after my recent deck replacement, i made some changes to the deck height and i need to lower this seat. but try as i may, i can't get the seat and pedastal off of the extension pole...i know that it locks on tight so the seat won't fall off the pole easily, but it can be removed, right? i'm thinkin' that it might just be corrosion or the like...any ideas? anyone had the same problem?
