I have 2 questions I hope someone with experience doing this can help with:

A. I plan on replacing the following. Condensing radiator was newly installed a couple years ago and is unused. Am I missing any must replace parts?

1) Aircon Receiver dryer - Part #1238300683

2) Aircon Compressor - Part #0002304711

3) Aircon Expansion Valve - Not sure what the correct part number is.


B. Any sequence of what to flush/ oil/ install etc.?

Many thanks in advance!

I'd replace all the hoses. They're ancient.
If you're sticking with R12, you may have trouble finding the correct expansion valve. The ones for sale now are made for 134a.
