Sill plate extensions

[Mjcre]

I've got a 1969 RR hardtop and it does not have the sill plate extensions. Were these standard on 1969 RR? If so, hardtops and post cars?
I have never paid attention to other RRs and wasn't for sure if this was a trim upgrade for GTXs and maybe sport satellites.

If someone could post a pic, it would be appreciated.
Thanks!

All cars had the extensions....It hold the carpet edge in place and fills the gap in front of the rear seat...
