[Roadsters] Gas and brake line sizes?

[Ken Oxenrider]

I am gearing up to replace all of the brake components  in my wife's 70 
1600 Roadster.  It has been sitting for 14 years under a pile of boxes 
in the garage.  I figure I need to replace it all, even the stainless 
steel tubing lines.  My question is, what sizes are those lines?  I have 
to buy flaring tools, tubing, etc. and short of buying calipers I 
thought someone might save me that trouble.  I don't even know if they 
are metric or SAE....
