Setting the A/C air gap???

I stopped by the AutoZone on the way home to see about getting the tool to set the air gap on the A/C compressor. They said the only puller they had was a 3 armed gear puller and it looks way too big. Dose anyone have a pic of the correct tool they can post so I can find the correct one? Thanks.

Autozone is full of it. They do (should) have the correct puller in stock. If you go to the Autozone website it will tell you what part number the puller is and you can take that number to Autozone and they will look on the shelf and see that they have it.

I went to their web site and found several pullers for A/C units. I just can't tell which one is the correct one for the Chevy Venture. Any chance you can help me out with a part number?
