We just started selling these CNC re-drilled rear stub axles. These rear stub axles come with a 5x114.3 and 4x114.3 bolt pattern. This will allow you to use 5 lug wheels on your S30. Many popular cars like the 240sx, 300zx and 350z have the 5x114.3 bolt pattern. You will need to get your own wheel studs. They are stock 27 spline 280Z stub axles with 280z companion flanges. They will work with any 240Z 260Z and 280Z axle. The 240z does not have the same spine count as the 280z but since these come with the companion flange they will bolt into your stock 240z axle.    Price is $300 plus you send us your original stub axles and companion flanges as cores or $450 without cores   TO ORDER GO TO OUR WEBSITE: http://www.silverminemotors.com/datsun/datsun-240z/suspension/5-lug-hub-stub-axles-for-240z-260z-280z   Let me know if you have any other questions.
