super stock shifter?!

The little red ball shown in your picture is a discontinued style Hurst reverse loc out.
The part sandwiches between the competition plus shifter box and the mounting pad on tail shaft.
The super shifter picture you have posted is a newer style with a loc out built into the
shifter box. Operating both are the same (lift the ball or T handle) but are completely different
parts.
The original hurst chrome 4-speed stick used is also discontinued.
The shifter mounting pad is also not the production line part
All of these parts can be hard to find used.
