Pulley size for 72 340 with AC

I'm currently looking at a pulley for a mopar block and the seller doesnt seem to have a whole lot of information, nor can I find the proper information about the factory part I need. I have a 1972 340 block with factory AC. The pulley I'm looking at is 5 1/4" diameter by 1 3/8" deep. Is this the pulley I'm looking for?
