it says they range from 1992-1996 but im sure, if you pick up a 92' it will be nearly identical to the 90'. except for the auto transmission...90' nissan used a different auto transmission than the 91-96's. bit pricey but worth every penny. also, check out ebay and TwinTurbo.net classifieds. sometimes in the classified section of TwinTurbo.net businesses will list manual's for the z32. good luck...
