secondary diaphragm check call

I have a similar situation, rebuilding a 4160 600 CFM (previously rebuilt Holley # 0-80319-1) on my recently acquired 1987 TriStar with 351. My secondary housing does not have the brass insert, but no check ball either. Could be I lost it during dis-assembly without realizing it, but that would surprise me as I have looked with magnifier and see no shiny spots down in the orifice that would indicate contact from a check ball. Holley kit 703-47 did not come with new check ball....does anyone know what size I need? I have searched for hours and cannot find the check ball diameter.
