This is GNP Smooth Shifting Combo #1
What this combo does is replaces the soft rubber shifter bushing and shifter stay and stiffens them up with a 90a shore strength polyurethane front shifter bushing and rear shifter stay. 
Replacing these, limits the amount of play or sloppiness in the shifter assembly, allowing the driver (you) to feel a more responsive and direct shift.
 
This is what you get with this combo
GNP's 5 or 6 speed shifter bushing
GNP's rear shifter stay and all hardware
5sp kit comes in red
6sp kit comes in blue
These parts install with simple hand tools in about 1 hour.
