Thats the way I did it, I put the hubs on the backing plate, than reassembled the shoes and the equipment for the ebrake shoes. So with the hub, backing plate, and ebrake hardware, I mounted it all in. I believe my tab, from the hub touches the backing plate, then I put the pin thing where the shoes hang onto. I tightened up the 4 bolts that hold the hub in the back, then the big 27mm iirc bolt on the back. From there I slid it into my axels.
I think I was going to cut off the tabs but was worried about the bolt shown in this pic, not being able to be threaded all the way.
