One Trunk Support Rod or Two?

Back in the 70's guys used to go to the junk yard and get the factory mechanism and brackets to weld on to the other side .Having 2 helps the hinges .I have a spare with brackets for the 64-65 I'd part with .Those screen door closer types are real garbage.The mechanical ones are way better . The rod pictured is something someone just put there to help hold up the trunk lid straight.
