I was in the same position you are but I didn't want ugly tabs or brake lines on my housing. I ran the front to rear line using the stock location, then used a T and ran a hard line tight against the body to the other side.
The hard line is secured midway across the car using a clip welded to the original rear end bump stop. I removed the bump stop because I'm running a Chris Alston 4 link.
I might have some pictures. Let me know if you want me to look for them.
Thanks for the help guys! After posting and thinking about it for a day, I will just run the line down the stock location and T off and run it along the body to the other side. I agree that it will look a lot cleaner than having the lines on the axle as well. I couldn't see the forest for the trees so to speak.
Kind of ghetto, but how about body panel adhesive ?? Grind off a tiny spot and "glue" the tab on.... if it can hold a body panel, it should hold a brake line tab...
