New spindles and the lower ball joint

[bmxmon]

Hey, Im doing the Granada swap with the left side done. The right side lower ball joint is giving me some problems though. While trying to tighten the nut, after it hits a certain point it just spins. (the metal shaft that the nut goes onto) I just had an idea about trying to get the spindle on there like before I knocked it loose, maybe with some washers. If it works I will tell you all asap, otherwise, please send some advice!
