my dad owns a 1988 fc and has sparco racing seats and 4 point harness and a cusco rear strut brace. he asked me to install it for him but taking a look at the instructions i came to realise how little japanese i know. he had the top harnesses going thru thetop of the seat right back down to where the lap belt is attached, i saw this and told him not to drive it and to get some sort of harness bar b/c it was unsafe.

anybody own an fc that has a cusco OS rear strut bar and can help me understand what i need to do to install it? or how to attach the top straps to the bar?
