Ford T80L-77003-A (gauge bar) thickness?

I am building a AOD Ford Transmission. Do you happen to know the thickness of the ( FORD, END-PLAY CHECKING TOOL ) part # T80L-77003-A . It appears that Ford included the thickness of the tool in the depth specifications. Without this information, it is next to impossible to set up the end clearance for the intermediate clutch and the clutch drum.
