i dont know if this helps anyone out with thier dp's but i am willing to install your aftermarket DP's on N55 non x drive for 100 dollars. i am located in spring valley. just pm me if you are interested it takes me about an hour and a half to swap it out.
also if you just want a place to do the swap and someone around to show you what to do i can help you for 20 as long as you do the labor.
