I am not at the boat. Anybody know what the factory tube OD size is for the stern rail and lifeline rail posts? 7/8 or 1 inch? I want to buy some hinged jaw slides for a couple of things. Bimini supports etc... year of boat is '98. C320 of course. Thanks, Scott Westwood scottwestwood at bellsouth.net H (919)-362-8538 C (919)-618-7185
