Help Identifying Speed Nut for Steering Shaft

[MST0118]

Can anyone post a photo or identify the source for the correct speed nut that holds the steering shaft cover on?

The P/N is 999.507.209.01 and the car is a 1972 911T.

Any help on this is appreciated. Thanks.

Here's a picture of the steering shaft but not sure what the speed nut should look like as it's a discontinued part. I found this picture of a speed nut for the luggage compartment but not sure if they're the same. If anyone can just post a picture of it, I'd greatly appreciate it. Thanks.
