That is assuming you are using the '69 ('65-72) Kelsey-Hayes disc brakes.
No disc, it's a 10 inch drum brake car.


If you plan on installing disc brakes, you will need the lower disc brake ball joints. When I installed the 73 Duster disc brakes on an older A body I used the 73 lower ball joints and the disc brake spindle. But that was a LONG time ago.
