Name this part
 

So I replaced my LCAs this weekend, as the bushings were shot.

Haynes left 2 things out of the manual though, the part a bout a T55 Torx, and the name of brackets that hold the ABS sensor cable to the arm. I currently have them held down with some massive Zip-ties, but would prefer to do it right.

So does anyone know the name of the retainer that they use to hold these in place?

You will need to get that from the dealership or junk yard.
I think your talking about the small plastic hold downs that just push into the LCA

the zip tie will hold I think
