Help needed - outer diameter AC lines

For my AC restoration project, I would need the outer diameter of two AC lines for a 69 Barracuda. Both are metal AC lines, one line runs along the passenger side fender from the drier to the AC expansion valve and the other line runs on the driver side fender, from the compressor through the radiator support panel to the condenser.

Thank you and Merry Christmas,

Wolfgang

On my 67 Barracuda, the liquid line (to the TXV) is 3/8" OD and the hot gas line is 1/2" OD.

Thank you Sir, that is exactly what I needed to know.
