schwinn stealth rear end?

i just bought a replacement rear end kit for my 2006 schwinn stealth 1000, wheel, gearbox, motor ect. I looked and it didnt come with a part im in need of, i still need a 4 hole piece that is on both sides of the wheel , that holds the wheel in place, and is supposed to cover the axel and rear wheel bearing does anyone have a spare, or know where i can find that part?
