I've looked at a 67 dual MC from Advanced Auto and the out ports for the front and rear reservoirs are not the same size. One was 5/16 fitting and the other (rear) was like a 9/16! Is this right? I thought the fitting sizes should be the same since the line is the same.

The larger size is 5/16" and the smaller is 3/16".
I was able to get a brass fitting for the 5/16" outlet from Pepboys. Obviously the 3/16" outlet didn't need a fitting with 3/16" hoses :)
