and save time/money doing it. I would do one of the following:
a) buy the 300zx specific kit and sell the universals (try selling them seperate, I think they would sell faster) b) sell your universal kit and enjoy the cash c) realize the easiest form of install of your universal kit is welded adapters onto the hardpipes d) call Coz/HKS and see if you can buy the hardware specific to the Z kit
