search "stanza struts", you will get a list of what you need to make sunny struts a straight bolt in

what year is your ute? if its a later model one you only need to change 2 things to make them bolt in

personally i wouldnt use sunny struts though, if you want the car to be low then you will need to get shorter inserts and cut the strut bodys down so that you have suspention travel. and also sunny struts have a different stub axle to all the other larger datsun struts so you cant swap hubs or anything

better off with some 180b or 200b struts
