first you need to know what gas your going to use that will tell you which compressor to get a sanden for r134a then you need a bracket for the compressor
speedyair has the brackets which you use with the hz lower bracket from factory ac .when installing the compressor you will need 4mm spacers for alignment
to bottom pulley. ok power steering goes onto first groove , second groove water pump alternator , third groove is your ac belt

hope this helps
