actually that reminds me, 240z 260z and 280z have a different bold spacing to attatch to the steering arm so wont work with the stuff i mentioned earlier
also on the more positive camber that stock point, R31 R30 S12 Z31 and 280zx all have a different stub axle angle that will give more positive camber than the other larger datsun struts. probably already said that in the first post though
