Hi, I had it done on my 997C2S and as you said, it consists of a different pivot point assembly at the gear lever and has nothing to do with the gearbox. You can either get the official Porsche kit which cost me $550 mounted by dealer or get a cheaper aftermarket which includes only the different parts that are then swapped as opposed to the assembly at the gear lever point which is simply replaced in the case of the official kit. Difference in price was onlt $200 so i went with the official kit. Quite happy with it...
