I also got the clip for the brake line where it runs across the rear axle today. The passenger side had one but not the driver side so I added one. It keeps the line away from the flanges on the axle so it doesn't rub, plus it holds it securely. The flanges stick out over an inch from the axle so it's not good to just zip tie it because it will rub even though I had put a rubber hose around it when I did the brake conversion. When the line was connected solidly to the back of the drum brake backing plate it wasn't as critical since it couldn't move much but once I connected it to the stainless flex line it needed to be secured. It's the little things.
