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

this is before I had removed all the black paint, does have the shifter lever.

I'll guess that is a 66 A-Body Standard 4 speed trans. What is the casting number on the tail housing? The shifter mounting plate looks like an Inland. That is why the 68 up shifter is not positioned correctly on an early A-Body. Probably tight through the small 64-65 hole in the hump. Yes, that is my Inland shifter assy on one of my transmissions.
