Where does this grommet go?

[GSS]

What is this grommet in my 1972 A-body grommet set from Classic Industries?

 

[Murray]

Firewall/ clutch.

 

[CRUZE 418]

Yes.

 

[GSS]

That explains why I didn't recognize it

Thanks

Could it be for speedometer cable?

Clutch rod that comes off the pedal and connects to Z bar. If you have an auto you will have a body plug in that hole.
