This is an Air Conditioning Parts Kit that includes a New Sanden SD-709 Compressor, New Expansion Valve, a New Drier, a set of O-rings, and Ester Oil. This should be everything you need to install your new compressor with all of the parts that are also required for the warranty. The warranty is 2 years. The compressor is a New OEM unit. The other parts are aftermarket. We have a cheaper kit that uses a new aftermarket compressor.
If you have an 87, you want to confirm exactly which compressor you have. Some had an early version with screw on fittings (SD-508). A little later in 87 they went to an SD-508 which is similar but has a thinner head (butt end of the compressor). If you have a question, please send me a picture to confirm.
