I've asked in a few places but can't get an answer.

Is the steering knuckle on the ST the same as the 7A-FE Corollas? How about the 7A-FE Geo Prizms?

I need a front knuckle for my car, but they are impossible to find! I'm hoping I can use a substitute.

How about 5th gen components?

I heard 5th gen springs and shocks work on 6th gen but please ask someone else before cause I'm not certain, i just heard it.
