I hope this mighht be an answer.....
It looks like the bracket and pulley shown will mount in place of the a/c compressor.


It shows: #3 Bracket 5303 0959
#4 Pulley 5303 1045
#5 Screw and Washer M10x1.5x45 6505 487AA
#6 Screw and washer 6504 344
I would
GUESS that the hardware is the bolts that are otherwise used to mount the compressor... ?
At another page, it is shown that there is only ONE part number for the belt; i.e., there is not a different belt depending on whether it has or doesn't have A/C.
