G'Day,
The Receiver / Dryer Unit is normally a throw away Item, not much point in shipping that.
It is used to remove any moisture from the System. Once opened to Atmosphere they are Cactus.
I don't need them, But Thank You for being Generous. So Many are only interested in Old Mopars for the Amount of Money they can Make.
Wish there were More like You.
