A833 (1970) Which Hurst Mechanism do I need for my 68 Barracuda?

I’m glad I found this thread. I also have a 1968 Barracuda with a 340 and would like to convert to a A-833. It is a 71 transmission. I do have all of the shifter linkages, but no shifter. I also have an auto center console at the moment and sounds like it’s possible to do this swap with my set up. I’m sure I’ll be asking questions on this thread at some point.
