Modern Vespa

I recently re-assembled my VBB cases and had a bit of trouble with the bearing set for the drive shaft. My old set of cases with a shot out rotary pad has a different style of bearing I really like. One piece standard style rather than that 4 piece roller thing I have now. I don't know if the previous owner had it milled out to accept the 1 piece bearing or it is a model type. The cases in question are VBB2 cases. Any input or ideas?

Are the cases from Asia? Appears to have had a rough life.

I am going to say no on the Asia cases. I really don't know as this was a basket case and the rotary pad was so damaged I had to opt for a different set of case. The original cases vin looks factory. See attached
