Think you will be on your own to figure out pulleys. Packard only offered the single groove back then so nothing factory. Flackmaster is your best info but here is a bit more to contemplate.
As was mentioned, when Packard offered AC on prewar cars, it was driven with another groove off the water pump/fan pulley. Multiple crank/damper grooves for PS and AC didn't arrive until 53-54. Others would have to say if one of those setups would work on an engine that far back.
Several have added an item to the later engines by mounting it to be able to use a longer version of the existing belt. That would be only one item and difficult if not impossible if your engine has the 1" wide belt since 1" pulleys don't seem to be a commonly available item. Here's a photo of a 39 engine where the compressor was mounted low and a longer belt was used. I believe it was Gene that owned the car and posted the photo originally. I think it might be a 3/4 belt.
No idea if the 38 engine could be done the same but still leaves having to do something with the PS. Possibly you could get the fan pulley from flackmaster and mount the compressor high off the head as Packard did. Use the space where this compressor is mounted for PS and drive that directly with a longer belt.
If the later crank pulleys would fit on the 38 crank then one of our former posters has said that a 302 Ford racing balancer with removable weights will fit the Packard crank. Multiple pulley configurations are available for those. I don't know if anyone has actually tried a Ford unit so no idea if in fact they will work or what other changes might need to be made.
