Correct Part(s) for replacing compressor and Accumulator?

My system was converted to 134 years ago.
 
Just want to make sure I'm buying the right stuff.  I'm trying to get it done this week, so it's either Amazon 2 day delivery or try to buy them locally.

What is the correct part number for the AC Compressor Cutoff Switch?  The one that's on the compressor itself.  Trying to find it on Amazon.
 
What is the correct part number for the blue Ford orifice?  Again, trying to find it on Amazon.
