Afaik, the vendors will sell brand new gen bezels only as a kit; bezel and insert, you still need to find the bezel springs somehow. E.g. such gen kit is approx. $400 for SMP and $400-450 for older PO models, and it is only about the aluminum inserts. Frankly speaking finding a gen ceramic insert is almost impossible imo.
You mind sharing where did you find gen bezels/inserts?
