A833 shifter needed for A body

Hi;) This is what I have.

"Are you going to run a Standard or Overdrive transmission? What linkage rods do you have?"
What's the difference between a standard vs overdrive? I have a 4 speed right? The shifter which was basically given to me doesn't fit the shifter mount. I have no linkage.
The shifter you posted looks really nice, but~ I'll give you a call around 10ish, I'm headed out to cut some of the tunnel for my "new" shifter hump;)

Is this yours? I'm a little confused
