Try calling ac or Neptunes this is something they normally have though pretty pricey.
For specifically spears you might find cheaper online if your not in a rush. Some of the local ones I found kina lack good quality. No idea on the place he refrenced never heard of them, just a few more options that came to my mind if that place doesn't pan out.
Pretty sure Grainger still carries Spears. Also, there are irrigation supply houses in the East Bay, probably all over the Bay Area, which I would try.
