Mike, I think you're a bit late on that one. :willy_nilly:
On the early Stalkers (such as mine), the V6 cars used a--at the time--late model V6 Camaro five speed tranny. The shifter housing exited beneath, and mostly forward of, the center dash panel that butted up to the trans tunnel which, in turn, gave rise to builders coming up with various solutions (see photos below) such as remote shifters, remote linkages, shifter mods, etc. The car in the add has a shifter handle mod (perhaps self-built or a 5.0 Mustang unit such a Steeda, etc.).
