I use my local Mom & Pop hardware store and their spring section. Get an outside diameter and length reading and then it boils down to wire size which seems to equate to tension strength. I don't know how it is in Pittsburgh, but in Virginia you can find the springs between painters pants and bird seed. Should be right next to the mailbox selection.
