4 speed pedal rebuild

So I do not need the plastic bushings, just:

1 - CP-ASH CLUTCH PEDAL SHAFT .5625" DIA 1967-72 A-BODY HEAVY DUTY PEDAL
2 - CPB98 CLUTCH PEDAL BEARING A-BODY
2 - CPBS CLUTCH PEDAL BEARING SEAL

Then weld the pedal shaft to the pedal.
I know the washer trick to get the spring out.

It looks like the pedal assembly is attached to many things.

Can all of this be accomplished with the pedal assembly still in the car?
