I tried this modification several years ago, but have since traded

the lens for one in better condition, so I don't have it here in

front of me, so I don't remember which direction I turned it. It was

simple to do, as you described, but be aware that the screws aren't

Phillips head - the are "cross-point", and a Phillips driver can

damage the screw heads.
