84 C10 Automatic to Manual conversion
 

I recently purchased a 1984 C10 305 auto.
I want to convert it to 4 speed.
I have a Muncie M20 with old manual clutch linkage bell housing.
But, confusion runs rampant when it comes to adding the clutch pedal.
Much of what I see were intended for use with "Hydraboost" brakes.
What models of trucks were these used in?
Will those pedals not work with vacuum brakes?
I may end up with a hydraulic clutch setup.

Any guidance from the members?
Thanks.
