For roller D1#F2.008X6.3E, production assembly in line no. 3 for make FG A0#RAB8.3X17X6.5 but roller D1#F2X5.3E, production assembly in line no. 5 for make F/G A0#RAB14.6X25X6.1A-1 which it impossible to mix in assembly line. And I check with production them confirm to clear line every time before change model.
