Do you want to restore it to new appearance and operation or just get it working again? Classic Auto Air can restore your components (compressor,dryer,hoses...). If you just want to repair the system you can purchase parts like compressor/dryer/expansion valve at the local parts store. I used a reman compressor, expansion valve and dryer from the parts store on my Charger, I was not happy with the dryer(it was a little different than original and pressure switch didn't fit but I made it work. I flushed the hoses/condenser/evaporator, evacuated and recharged with R12. It works great but I wouldn't call it restored with the old hoses and incorrect dryer.
