1968 Chrysler battery tray, what is this bracket?

[bronze turbine]

It says this is used on a 1968 Chrysler C-body battery tray, but my car didn't have this. Is this used on a '68?
If so, I'm not sure where/how it attaches.
Thanks for any help.

Here is where it is on mine. Bottom bracket support.
