yeah,basicly i do already have a 5 stud hub,and the studs just need to be longer.but it would be almost impossible to get the shorter studs out of the hub i have,because the back of the hub is not flat.it was really only ever designed to fit 4 studs from behind.i was able to re-use one of the standard hole positions but the other 4 had to be drilled,tapped and then welded from behind.it was not a fun job.so i though if i could get a hub with 5 studs already in it,i could just change them with long ones without any mods. i think my hubs may be stanza,they have the holden bearings in them.and yeah, i was thinking skyline or 180sx,200sx.i am really just trying to avoid modifying another set of stanza hubs.
