for the front you use the 240sx se 95+ i doubt (but i can be wrong) the 300zx front knuckle and spindle can be used.
on the rear you can use the n/a 300zx (i beleive the tt version cant be used i could be wrong on this as well) or the 240sx se 95+
i have done the front conversion and my rear hubs are coming in this tuesday to be done <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='
