I'm installing my used dspec with no instructions. Figure they aren't much different than stock to install right? Well my rear struts came with two nuts each what's that about? If I install the sportline spring mount large brass color washer lock washer and a nut there is hardly enough room for another nut and the cap that covers the adjustment screw. If I put both on there would be no exposed threads and the cap wouldn't be down all the way? Any input? ??
