Most factory TH400 carbs do not have the arm extension that the ball or pivot is attachment point that is needed for a TH350 kickdown cable link. TH400 kickdown is electrical and does not need that attachment point.

TH400 trans has vacuum modulator @ front of pan, pass side.
TH350 has vacuum modulator @ rear of pan on pass side.
Powerglide has vac modulator @ rear of pan on drivers side...
