Master Cylinder Pushrod Retainer Question

OK so maybe my 67 is missing a part. If the center hole in that plate isn't small enough to capture and retain the master cylinders guts... I dont need one. while I'm thinking about it... I honestly can't recall if the boot is present or not.
I know have the one sheet metal tab in place at the upper hole. I did briefly consider transferring the tab from removed master cylinder to the lower hole of the new master cylinder but had a second thought... a fluid leak would generate rust down there. I might never get that screw out again without a drill. I have brakes. I'll undo my disagree above before yall start shooting. Again, good luck to all.
