SLC ball joints?

I took my suspension apart and am looking to install new ball joints. The only markings on them are "OEM" and the number 40407 on different areas on the piece. Lots of googleing and so far no joy. I think I found this once before but it has slipped my mind. Can anyone point me to a part number for a Moog or other high quality ball joint to suit.
