if you want to have the pinion right take out your axels then swap the backing plates side for side rotate them 180degrees then rotate the axel until the brake cylinders are at the 12oclock position and you should be pretty close ,the way you have it set now it looks to be about 20 degrees off and i think the way the u bolts are that the rear can just torque itself right out of there having the u bolts around the axel tube would be a wise move
