87 Hydraulic Clutch Questions

[ext5060]

Hello gurus.
I am embarking on my first ever auto to manual swap in my 86 GMC shorty. I have a set of pedals from ebay but I have a few questions as I am not sure what parts are needed for it.

Attached are pics of the clutch pedal and the brake pedal.
1. Is there any other spring to return the clutch pedal? What is the little
spring do that is pictured?
2. On the brake pedal, no spring was sent, I assume the spring hooks up in
the indented portion under the brake switch and attaches to the stub on
the brake pedal.
3. Do you know who sells replacement springs for the clutch and brake pedal.

Thanks

James
