Copper from memory....major pain in the #rse to do correctly. A/c re-gas about 12 hours (if you know what you are doing!) and a new heater core.
HC 0025
That should be the part number from Covs and Repco.
Seriously, centre console, steering column, dashboard, wipers, heater box......BIG BIG BIG job!!!!
Do not expect any change out of about $700 all up minimum.
