Hi

I have been looking at Napa for the kick down switch that is connects to the accelerator pedal I have the st300 transmission does anyone know the part number that I can use besides going to special parts places to get it

 

I'm not sure if you'll find it at Napa, but it is the same switch as the Turbo 400.

What year? The ST300 was used from 1964-1969. The switches varied depending on the year and model

 

It’s a 68 cutlass

 

The switch is the same as for the TH400. All the repro houses sell them.
