5.2 Magnum swap into 70s-80s truck

Good point, Hotlines. Maybe it was cheaper to add a switch than to rework the detents on the shifter pawl? That, and instrument panel display would've had to be changed as well. For a truck platform that was a couple years from being completely updated, the switch was probably the cheapest, easiest option. Why the button wasn't done away with for the 94 model launch, I have no good ideas.
