Lopi Leyden upper auger bushing removal

[Maintain 4 life]

Hope you can help, I have seen a lot of auger removal and lower bushing removal on this model. I have not seen anyone writing about the upper bushing removal from the lopi leyden. I can see the two threads from the screws holding the busing plate but not the screw head location.Any advice on how to get this out would be appreciated
Thanks

From the picture it looks like you have to remove the drop tube assembly to gain access too the bushing retainer screws.
