Factory, original parts, i did send it to Classic Auto Air "sales@classicautoair.com" in Tampa, it came back like new, with corect oil and all the original stickers on it I also gave them the hoses to make new ones, had a bit of truble before I found a container with R12 freon, it is no longer in production and the new ones does not cool as good, but you can also use R up to 21 i think, the gays in Classic will tell you. Be sure to use the parts you took off the car, there is several parts that look almost the same but that is different on a air cond. car, for example the fan starts automatic when you turn on the air cond, importen for not overheeting the coolant.
