Talk to Allen at Allen's Off Road, I do believe you can purchase parts "ala carte". Pretty easy...You read my install write up and saw the pictures right? Just kidding

Easy no, but pretty straight forward. No instructions came with any of it. I would be more than glad, once you have all the pieces and parts, to provide you with the real important steps. There are some issues that aren't addressed in any of the online installs, example the rear sway bar. The rear sway bar will bolt up but, the angle of the sway bar links from the frame to the swaybar is so extreme they bind under the least amount of articulation and don't effectively dampen body roll on or off road. I solved that by fabing up some new frame mounts and welding them farther back on the frame so everything is perfectly lined up. No issues with the quality or durability of Prue Jeeps stuff.
