Lee 30.06 seater die stem thread specs?

[Vettepilot]

Strictly for convenience, I would like to add a micrometer adjust stem to my Lee 30.06 dead length bullet seating die. Does anyone know the size and thread specs of the Lee seater stem? (I am in "the city" for two or three days to buy supplies and don't have my die with me to measure.)

Thanks in advance!
