'68-'69 Barracuda Ralley Dash only

So, there's been a discussion about a metal brace that is specifically on the above said dashes only. I've checked my parts book and find no mention nor picture of this "stiffening" brace. Below is a picture of that brace but it has no p/n or Pentastar on it. Does this part actually ONLY come on ralley dashes for '68-'69 Barracudas?
I also have included a picture from my Chrysler parts book. I have never had a ralley dash apart so I'm curious why only stiffen that dash?

That plate is the anchor point for the screws that attach the Bezel to the dash frame. Without it, the screws would just go through the bezel and not secure the bezel.
