How do i find out how all the belts go on the pulleys on a 1988 Chevy Nova with ac and the carbed engine?

There should be a diaghram, showing belt routing, under the hood - sometimes on the hood itself, sometimes on the metal/plastic obove and to to both sides of the radiator. If factory decals are missing, auto parts businesses will have repair manuals for sale that include routing diaghrams - if you can remember just by looking, an unwrapped book can be looked at for free...
