I hope you didn't remove your waterpump.
In that picture it looks like they used a humongus custom idler pulley for the power-steering belt tensioner. And I strongly suggest you find an idler to replace the airpump pulley if you've removed that. Without an idler, you'll have very little belt contact with the water-pump pulley and it will slip. It's not improved much with under-driven pulleys. You'll be tempted to over-tighten them and that can lead to more trouble....even front main bearing damage.
A couple threads to consider..

^I don't think you can get mine anymore. But this thread mentions another alternative to pineapples.

If your still intent on removing it, use a piece of string to get a measurement, take it to the parts store and look for a 5 rib belt that's close.

Well belts are just coded by lenght. So, if you measure the 'length' of both the 5 (5PK) and 6 (6PK)ribbed belts you will get to a ball park figure. Rem, when measuring, set the alternator and the P/S ider pulley 'down' so you have some play to adjust the new belt as it stretches. I also recommend / agree with sgtblue that the belt contact area on the W/P pulley is insufficent without an idler pulley. I have made a custom one - so if you have the tools and skills you can do it yourself. Jeremy

^The Garfinkle pulley does...one of the reasons I went with it. The Pineapple idler requires a shorter belt but will probably be the easiest one to get. I think Chadwick's does too. But most importantly they all keep good belt contact on the waterpump pulley.

I just purchased a totally stock non-turbo, '91 RX7; what belt should I be buying for my tune-up?

I have A/C and power steering, I believe that matters but obviously I'm asking for help for a reason.

If it's totally stock the parts store should be able to get you what you want.
