I bought an 88 P2 and my father in law and I are refurbishing it. It is a PITA but we are making progress. Carpet stripped, cleaned the disgusting mess in the bilge, cleaned the fuel tanks and started wet sanding. We ran into one issue. There is a metal plate on the rear deck where the rear seat post meets the deck. It is on top of the deck but there is carpet under it. There were four bolts holding it down and we removed those but it still wont come off or move. It is something done by a previous owner as Bass Cat does not do this. Anybody have any ideas how to get it off?
