Danny(Austin) is right on the Pricing of Stillen Gtz-R kit but you don't have to use stillen. Wings west has a urethane kit that retails for $969 and plenty of wings west dealers including myself sell them for less. Also Bomex makes a nice quality fitting kit although it is fiberglass and they range from $900-1200. Not to forget you can do the 99-00 fairlady front bumper for under $900 shipped. These are just a few.
