the 57-61 fury uses the K772 upper ball joint and the K719 [screw in] lower joint on all models. the lower joint has the same taper as the 74&up B body spindles [which also uses the K719 screw in lower joint] with the steering arm having the taper in the steering arm instead of the lower control arm. so score a late set of spindles [F,M,J body], caliper brackets of your rotor diameter choice, and the steering arms. the tie rod tapers are the same also. you may be able to use your existing steering arms, but i forget if that's possible. the only other thing you need to do is shorten [i think] the tie rod adjuster sleeves to get the proper toe adjustment. and if i also remember correctly [at my age, the "remembering correctly" statement is, um, kinda related to "oldtimers" ], your original spindle is the same height, or real close to, the late model "tall" spindle some guys are afraid to use in their A and B body conversions. hope this is of some help to you.
