use all the same stuff as for stanza struts...plenty of info around on the site
and just need to use smaller spring perches or coilovers

fitting them into a 120y, you can either go a whole 180b front end. crossmember LCAs castor rods and such
or if its a late model 120y all you should need to do is change to stanza or sunny steering arms and the 180b struts should go striaght in

if its an easly model, use all the stuff that you would need to fit stanza struts...except for the stanza strut
