ctek brake rotors and -67 hub. problem!

Hi all! I bought a small bolt kelsey hayes brake kit to convrt my 66 dart tp front discs and the kit included stock 67 spindles and ϧcontrol arm and hub but when i mounted the spindle, bearings and hub and tried to put the rotor on the hub i noticed two things, one is that tthe rotor hits the outer edge of the hub before beeing in place and second is that tje outer diameter of the hub is much smaller then the hole in the rotor, ctek part number on the rotor is 121.63005 have anyon else had any similiar problems?
