More progress has been made!! Got the backing plate brackets mocked up, and tacked to the housing.
Here is our initial mockup. Took a couple of times of mocking everything up, taking it off, and adjusting the bracket, before we finally got it where it needed to be.
since the rotors were 6 lug and the axle is 5 lug, I had to drill holes to adapt it. To do so I took a pair of vise grips and clamped this rotor to another rotor for a Jeep JK I had laying around since the jks use the 5x5 lug pattern also. And if you are like me, this photo gives you a headache trying to figure out which holes are for the 5 lug, and which are for the 6 lug. But it definitely works good!
These last 2 pictures are everything all mocked up.
