I don't have one. Or, all of one. I have half of one attached to my axle. You can actually see it hanging down near my passenger tire in the pictures.did the one you tried to install was too long? or were you missing one altogether?
if it is "too long", it does require some nutbusting to get it in.
just looked at my receipt.
Raybestos part # 4351166B
HOPE THIS HELPS!
