Need Help Identifying This 3 Belt Crank Pully from A 273 Commando Engine With A/C

These are the pulleys with the rubber damper on the outer A/C pulley. The one I posted pictures of at the top with the number stamped in it does not have the rubber damper A/C pulley.

The original A/C pulley has an isolator (thick rubber section). That isolates the vibration from when the AC compressor comes on. They were used to ensure that there was no chirping from belt on the front end accessory drive units. A solid pulley will also work but may make noise. 65
