Just to clarify, all datsun/nissan struts save 1200 and 120y up to and including R31 skyline(i havent looked at R31) and 280zx will bolt to a stanza or sunny steering arm, the sunny lower control arm is same length as a 1200 one but will accept a larger steering arm and ball joint. So you can use the sunny control arm with other struts to keep the same 1200 width or if you want wider track use the stanza arm. Then instead of having to modify 120y castor rods like every one does use the sunny rods. The sunny ball joints and the stanza ones are the same. Use stanza or sunny outer tie rods and stanza sway bar links because these are thicker. And i think that is all.
