i have the same cusco roll cage as the tacker minus the side bars. Can you confirm if that is the chrome moly one? I have been lead to believe that the blue ones are the chrome moly ones and the black ones are the normal ones. I havent done a comparison in weight with a friends one who has the black one.
and just to reconfirm what beer baron said, its a pain in the ass assembling the cage inside the car!
