I need to know from anyone who has installed rear upper control arms on a S13 if you need two people when you put them back on. Of course to get the stock RUCA's off you have to take off the rear struts but unlike the front struts where you can put them into place and bolt them on by yourself because the mounting points are right there in your face...the rear strut mounting points are in the trunk/hatch. Would you need one person to feed them through the mounting points while another person reached into the trunk/hatch and bolted them in or can you bolt them up to the spindle or just position them so that you can then get to the trunk and bolt the top in?

 

i was able to install coilovers and RUCAs by myself, with the help of a jack.
