Couple of questions.
I have a 1982 244 with the old r12 system for the ac
York + basic drier without any electronics on it, here are the photos:

I plan to add:
-a used later style compressor + mount from a 760 or 940 to replace my york r12 compressor
-o ring kit, new drier, new expansion valve
Here are the basic parts I plan on ordering:
Four Seasons 38607 expansion valve

Four Seasons 33264 Drier
https://www.amazon.com/-/es/gp/product/B000CZ340Q/ref=ox_sc_act_title_2?smid=ATVPDKIKX0DER&psc=1
universal o-ring kit
only 1 of the hoses in the current system is not new.
I already checked with a test light that my compressor on-signal is working from the instrument switch via the green wire.
Should I clean the system out with the older parts not to contaminate the new drier and expansion valve? I am re-using the condenser + evaporator core.
I plan to suck out the system and wait a couple days (instead of an hour or so) to make sure there are no leaks.
I am also worried about the combination of "whatever was in the system" vs. adding Pag, Poe, or Ester. In my country esther is more available than Pag. Poe is impossible to find.
I have read the dave barton guides and numerous others here but still have uncertainties about fitment of the expansion valve+drier and my plan.
