You need to first, get a A/C compressor belt. The compressor itself just bolts to the block. Theres a bracket that bolts to the block, which is actually a engine mount. Once you get it bolted up, you have to take the PS belt off the pulley, and slide the A/C Compressor belt on the pulley, and then re-install the PS belt. After that, its all cake work and self explainatory.
