Anybody know where this goes in engine compartment

I could not ID it by the picture, maybe it's too clean & shiney...
Is this a piece that is specific to Dart Sports? Or only V8 Sports & Dusters? Only on the left frame rail?
Like I said, I couldn't ID it and I have '72 & '75 Dusters that I have torn apart. And it goes around the tie rod ends?
This is not the plastic piece that goes over the strut rod is it?
Thx,
C
