1967 Barracuda Steering Component Help Needed

there were two of the mopar disc sizes used on that spindle. One is roughly 10.5 and the other is 11.78 I believe. the larger requires 15 inch wheels atleast {mopar wheels that is] the both will fit that spindle with the correct appropriate caliper adapter. all the 73+ A bodies used the smaller Disc. All of these spindles used the larger ball joint. Only the pre 73 [72 and down] disc brake cars used the smaller upper ball joint but you can spot them easy cause they are the 4 piston kelsey hayes setup. It is possible that some sort of balljoint adapter could have been used on the ball joint stud to adapt the smaller ball joint. I canot tell in the pic what ball joint you have. Ob viously you could measure them if you had some dimension info. {dont have that at hand]
