Default Brake lines

I order a set of brake lines for a 77 corvette with PB,Automatic ,they sent me wrong set,sent set for 68.I called they sent another set
the lines from the Master cyl. to the proportitioning valve are wrong. The lines they sent one line has 9/16 barrel on both ends. The other line has one end 1/2" the other end is 7/16.I called and told them they were wrong lines.They are telling me they are the correct lines.My lines I took off are 1/2" on one end ( for porportion valve ) and 3/8's on the other end ( for the master cyl ). both lines .I want to make sure that the porportion valve was not change during cars life time ,which I doubt that it was changed. so when I call Monday if they still say I have correct lines I will just send them back.So if someone can verify
that my lines need to be 1/2 on one end and 3/8 on other end.I will be greatful.

Thanks
Gary
