Source for ZJ pitman arm?

I'm wanting to get rid of my Rusty's 4" drop pitman arm and go with one from a ZJ since I think it's a little more drop than the factory XJ piece. Problem is I've called Autozone and O'Reilly and they said they are no longer available? Any ideas on a source?

JY, you try moris4x4, teamcherokee.com etc?

Not sure if its the cheapest but here you go.
