seeking info on rebuild kits

[ArmyAnt]

Recently acquired a 1964 L320. Its currently not running. According to the PO, it has the E1 engine. So I started to tear down, replace or salvage some parts. I started with the clutch.
I attached photos of both the clutch master cylinder and the clutch slave cylinder. They appear to be salvageable...Could someone help out with links or part numbers to any rebuild kits that would work on these. The carburetor is next...also would be needing a rebuild kit for that as well. Later on...I'd like to covert from generator to alternator...anyone else do this? What works as a good alternator setup?
Thanks in advance for any advice.
