1966 dart power steering info

hey everyone i have a 66 dart with a 273 without power steering and i want to install p.s on it,now i have a p.s box from a 73 duster and a pump and brackets from a 69 dart my problem is i have held the pump up to the motor and cant see anywhere that it would attach to the motor then i saw a different style pump an older style but i have studied the pictures and cant see where it would bolt up either i think im missing bolt holes in the block.i will try to include pictures of what i have and the front of the motor and if anyone can offer advise it would be greatly appreciated,thanks
