1968 Chrysler Newport Custom 383 Non-A/s Water pump pulley

Looking for a water pump pulley, non a/c 383 single groove, I measured the one I have now and it measure 6" 13/16 diameter. Seems like an odd measurement.

And how deep is it? Either inside depth or overall height, overall is a bit easier to measure.
