Do you know why it was left in that state?
Consider a new compressor, aftermarket drier is fine, a parallel flow aftermarket condenser (someone please comment if parallell is no good for R12), AC flush for the lines and evaporator, coil cleaner for the outside of the evaporator.
Search for how forum members have figured out workarounds to get the outside of the evaporator clean. It improves the airflow and gives a lower air duct temp.
It is a big task but doable. Good luck!!!
