Federal Power Steering Pulley

I'm looking for a federal power steering pulley for my 1970 Duster. I bought one from a fellow member but the shaft size is incorrect for what I need. I need the pulley to be 7 inches in diameter with a 5/8 shaft size hole. Please let me know if you can help. Looking to spend between 20-30, but I'm reasonable. I live in CA, in the SF Bay Area, zip is 94580. Thanks for looking guys, appreciate it.
