K/D super servo's

For the street,,just buy the MP shift improver kit for 727, it has a new blocked 5/8" piston in a new servo. Block the accumulator down with a metal tube. Then add the Transgo kit for the valvebody. Or leave the skinny rod servo that is standard in an La 904-9, it does not have a staged apply. But its weak due to less diameter, to keep steady when extended. Add shims to the rear apply servo to hit harder.
