Need Pic of 4.2 w/AC

Need a picture of the pulley system off a 81 CJ with the 4.2 and with AC please. I have an idler pulley on mine that:

1. Not sure if it belongs there
2. If it does belong there not sure its the correct one/setup

Anyone?
Someone has to have a 4.2 with AC and the V-belt setup.
Need a picture of the idler pulley for the alternator and AC compressor.

My 304 doesn't have a idler pulley. Where is it located?

I believe I have it figured out. Let ya know as soon as the belts get here.
Looks like the PO rigged up some type of idler pulley for the alternator. Alternator does not use one from the pictures I found on line.

I agree. I've never seen one for a v belt on a cj.

3 grove crank, one grove water pump. Outside crank grove goes to alternator.
Middle grove goes to AC compressor and over to idler pulley to the left of thermostat housing. Back crank grove goes to water pump pulley and power steering pump.

At least that's how I think it goes

That is different than mine. I am going to put dual belts on my alternator and York.
