i have an h23 that i am swapping into my cb7 accord and decided that i dont want a/c. what is the belt part number that will fit from the crank pulley and alternator alone?

 

If you can't use an OEM p/n belt, your best bet would be to use some string and run it where you want the belt to go(crank and alt pulleys in this case). Pull it taught, and make sure whatever tensioning mechanism your alternator uses isn't at its maximum adjustment(you want room to tension the new belt). Measure the length of the string, and that, along with the width/number of ribs from your original belt should give you enough info to get a new belt from your local parts store.
