I have a +/- 40 year old Daiwa saltwater spinning reel, I think it is #4000 (emblem warn off). Still works great but I cannot get the metal side plate off to grease the gears. the plate is held on by 3 very small screws. the groove in one screw is mashed. The side plate has a curved rim so I cannot remove the other screws and lift it up to expose the screw shaft. Partly recessed so there is not enough to grab with pliers. I really want to keep it going. any suggestions?
