For the spacer, PM Flex. As far as I know, there isn't a website set up for ordering.
And I believe that people only use the crank pulley becaues that is where most of the power gains come from. If you have a big stereo system, it's not recommended to use the alternator pulley, and with the headgasket problem, not a good idea to use the water pump pulley.
It's your choice though - I've seen other people who use all 3 UD pulley's and have no problem at all. I would just use the crank pulley since the other don't really make much of a difference, but it's your choice. Also, if anything I said was wrong, please correct me. I don't like passing on bad info.
