Larry Stock Pantera Parts Connection in Carson City sells rebuilt brake components. I'll let others chime in with that as as an option as I have not tried him personally. https://www.panteraparts.com/
Search this forum for the clutch master as there have been many failures of cheaply made repos. If I needed one, I would go with an Alfa unit from ATE or Centerline. There is a very long thread on this topic recently.
For AC, I live in San Diego, so the weather here is very mild, but even if I had AC that worked, I would never use it. Just my view.
Good luck and welcome to the madness.
