Kaminari kits were very expensive back in it's day, about 1983...I know because I had a 78 280z and bought the front air dam and rear tail, which I had moulded in and came out super!! just for thought, the front airdam back then I paid 250.00 and that was a wholesale price. same for the tail. I believe if Im not mistaken that the whole kit with the wide body panels and front and back spoilers ran about 3k. not installed...that was a whole other issue...these kits no longer are made...hope this info helps...Rob
