As the title states I am currently looking for a diagram to ensure that this California Z, belts are correct. When I got the car it was missing half the belts and then again some belts appear to be bypassing pulleys. Ive checked out a few websites and forums but have not found a decent diagram. Anyone have a nice diagram or even a decent looking picture of a Z with a smog pump? Thank you all for your time.

Welcome to the club.

When you say "missing half the belts" I assume you mean missing one belt out of two. There's really only one belt that matters and it forms a triangle between the crank pulley, the water pump/fan assembly, and the alternator. Without this belt your car would quickly overheat before even getting a chance to drain the battery. The tension on this belt is adjusted by moving the alternator itself and there are no other pulleys involved. If you still have the air pump there would be another belt strictly between the crank pulley and the air pump. It would ride the crank pulley one groove closer to the radiator than the first belt which is closest to the engine. Finally, if your car had aftermarket air conditioning there might be a third crank pulley slot even closer to the radiator. Some aftermarket A/C units were mounted on the right side of the car below the fuel pump while others may have been mounted on the left, sometimes replacing the air pump. While I don't have the diagram that you asked for you might consider posting a picture of your current setup. Someone here will be able to quickly diagnose what, if anything, is wrong with your belts.

Thanks for the information. I will go grab some pictures later this week of the setup and post em here. Thanks again.
