Need help I'd my brakes please!

When I bought my duster it had the drums up front but had this disk setup in the trunk now the upper ball going is the small one and it does fit my bakes as well as the the balljoint for turning, but the lower balljoint is huge amending fit my lower control arm, if some one can tell me what they came of it would help. Thanks! Had to put a link to my album the bakes are the first five pictures.
