rear brake hose union location

[FL71C10]

I am redoing my whole brake system, and ran into a problem with the rear brake lines. I bought a new stainless line kit from Right Stuff several years ago. I went to install them yesterday and the lines are not the right length. The driver side is too short and the passenger side is too long.

My truck is 1 71 1/2 ton, coil springs.

Here are a couple of pictures. Does anyone have a picture of how theirs are? My tab is broken off the rear end housing so I could some help figuring out where that attaches as well.

Thanks!
