So by the looks of it i need two belts but due to removing most of the stuff you cant just search by type year etc at your local store sadly

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.

5 rib belt pulleys?
hmm.That may be in my Vocabulary..(hint,since you can't sell parts in Tech..lol!)

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

this is an awesome idea.. i was thinking the other day i could just make something like this. this would allow me to use the stock belts correct?

^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.
