Not sure if this clearance issue affected all JK's at one time, but I have a 2013 Sport and the pipe that crosses under the trans drain is far enough forward that clearance doesn't appear to be an issue.
I simply went out and purchased two bolts, one with a 17mm head and the other with a 14mm and put two nuts back to back at their centers.
Total cost for all of it was under $5. Going to order Redline MTL, which no local place has on the shelves. I will update if there are any complications with this setup when I'm done.
