I have a new Z-5 cargo rack for sale that came with my 2011 Supra 242 launch. New sells for $2400.00+ asking $1400 will ship for free. The top pins are 6' apart and the bottom pins are 5' 4" apart. There is 2' between the top and bottom pins. This should give everyone the measurements to figure out if it would fit on their tower. You can contact me at 336-202-5000 or firstname.lastname@example.orgIt is 6' tall, 6' 6" at the widest part of Z5 rack.
