No kickdown linkage?

So with a manual VB, no kickdown lever is even needed? Also, can you guys make a recomendation on where to buy, I see them everywhere! Some told me the cheetah brand? Can I do this with them trans in the car?
Easy to do in car. Doesn't take much longer to do than a filter change. Get the car on jack stands with the rear wheels . You will have to rotate the driveshaft to disengage the parking pawl. Might be a good time to change your selector shaft seal while you have the vb out.
