350 TBI Knock sensor and ESC module part# ?

Can anyone help me out with the Knock Sensor and ESC Module part numbers for a 350 TBI?

Would the 350 TPI sensors be ok?

What about the KS #10456549 used on 90-92 TPI engines?
Combined with the ESC Module 16128261.

The TPI KS used 90-92 engines has a different output impedance (3.9kOhm). TBI specific KS is around 100kOhm. ESC module is analog signal amplifier to pulse converter.
