Jay,
You have the correct part # for the regular cab application and yes you would normally put a R for Red or a G for Graphite black at the end of the part # to specify color. The website does not have a photograph for the Dakota here is the link
http://www.energysuspension.com/pages/dgt1.html. As far as the hardware goes, the only hardware we have ever provided with this kit is the swaybar sleeves, 4 washers for the endlinks, and steel sleeves for the I.D.'s of several flange bushings. But no bolts or nut are included in the kit.
This kit has always had 6 body mounts for the 5.4106 and never 8 so I cannot reimburse you for the mounts nor the hardware that were never a part of that set #.
Jay please call 949.361.3935 for further assistance. Thanks again.
