I may know a guy that can get you brackets.. PM me for details.
Actually.. The newer/current kit, has brackets for BOTH sides. So, steering is parallel. The brackets tie in to the knuckle below, using 2 of the 3 hub bolts.
For what it is, lots of money. But it is a plug n pray kit. I got one of those kits, used, included with an axle I bought last year. Have not done anything with it yet. Plan was to put it on my MJ when swapping to 4WD, but I have a complete WJ axle, and a parts WJ to take parts off, so probably will not be used. WJ brakes > XJ brakes.
