Thanks to Dick Benjamin;I checked with a local parts store and found that the usual size for brake lines is 3/16" and looked at some while I was there. That is 0.185". After I returned home, I rechecked the OD of the tubing on the car (cleaned it first) and saw that it really is 3/16" after all. I bought a "double" flaring tool and saw from the instructions that come with it what they mean by "double". During the process of flaring the end of a piece of tubing it first forms a bell shape and then the tool is used again to fold part of the bell shape back into itself which eventually results in a double thickness flare at the end of the tubing. It is much stronger than it would be otherwise.
First step will be to get the springs back on the shoes and then re-install the drums and then wheels and tires. Then I can re-configure my jacks and support structures so that I can safely get under the car to remove brake lines and replace them.
Thanks to everyone for their help and suggestions. Joe
