5 or so years ago when I rebuilt the front-end, I got mine from PST. I think it was about $100.

I had tried junkyard diving a couple times and found what I thought were solid ones, and they just loosened up after a few miles.

Ended up with the full rebuild kit (Poly Graphite) and bought the pitmann arm separate (Its an extra cost).
