Thank you for the donation.
For the year model, the system should be R12 freon and depending on region, it requires qualified personnels to work on it.
If the system has not been retrofitted to R134A yet, then I would advise against doing the job as R12 system is in the final stages of being phased out and the freon is getting more and more expensive and it could be an offence to work on it if you ar not qualified.
On the system it should fti if the year and engine model are the dame.
The complete A/C consists of the following that is not in vehicle:
6. Receiver drier.
7. Crank pulley.
8. Control panel ( switches for A/C compressor etc)
9. Cooling fan.
10. Wiring harness and relays.
For some earlier models ( pre 90 year) some vehicles have underdash harnesses that have the complete system wiring in them and you need only to plug in and it would work, but this should be checked.
How ever it must be noted that for the A/C compressor, cooling fan and pressure switches in engine compartment, it has a separate harness that is not present in non A/C vehicles.
