Seriously, some shops have parts on hand from old equipment. You might check around. Other than that, tapping the screwdriver handle with a plastic mallet will sometimes help loosen them. Get someone to support the lens. Then while holding the screwdriver in the screws slot, smack the driver's handle a few times. The shock transmited to the screw can help loosen it. But you will need drivers that fit the screws perfectly. Paul -------------- Original message ---------------------- From: "P. J.
