Need a Favor! Nuts on Master Cylinder.. Sizes??

[Kdubslugga]

Im replacing the master cylinder and brake booster and i have a knack for using the wrong size wrenchs, i use metric when i should use standard and vise versa. Im going to get some line wrenches so what sizes do i need?? Im looking for the sizes to fit the 3 nuts that are on the end of the brake lines that go right into the master cylinder. Thank you ahead of time!!!!

I may have found the answer but i need it confirned, i believe they are standard sized nuts and i'll need a 1/2 inch wrench and a 9/16, is this correct????

Just took mine off the other day, they were either 14mm or 9/16" if I remember right.
