Actually there's no need for either the bearing ring press in lip or the fingered bearing retainer (I hope these terms make sense). 11 loose balls will fill the cups properly and FB's suggestion of using grease as a "glue" to hold the balls in place during assembly is the usual method. Grease up the frame shell and threading. Grease should get squeezed out on assembly (that way you know you have enough). The RH cup needs to be VERY tightly installed. Place the RH crank arm on the spindle after initial BB assembly and use it as a lever to determine bearing adjustment with.
Or just get a sealed unit. Andy.
