Stanza struts, or 240K early Skyline struts modified with adjustable height platforms and top hat to a suitable spring. You should really look around for a competent suspension specialist. Brakes are a pick between the Stanza setup with Bluebird rear disc as they are a match same as the Blubird TRX ,or 200B disc and calipers (the Girlock or Girling types I can't remember now which has bigger pad area) they fit straight on the Stanza Struts. Or use the Stanza brakes with modified discs and calipers. 180sx disc with Hilux calipers,
or some disc?? with commodore calipers.
argh I talk too much too many options
