You have it straight, there appears to be a simple stick swap! The short stick stuck onto the a/stick mechanism. The cars with the short stick have a big boot to cover the junk.

Short story, most likely the same shifter, different arms, same price = no optional a/t shifter, just the a/stick which is indeed a dual gate!

I started/stopped typing that reply several times here, so probably got lost in it myself
