Suitable replacement for a Chev CMP fuel pump and brake cylinder?

[Pedro Bedard]

Hey all,
My restoration has finally begun. However the brake master cylinder is... missing. I'm not sure how the previous owner used to stop the truck (it was used as a snowblower) but the cylinder is gone.

Also, the fuel pump is seized.

If anyone has reccomendations as to suitable replacements for these, I'd appreciate the suggestions.

Cheers!
