Default 65 master cylinder

Can someone post a picture of how a 1965 GTO single master cyl. to proportional
valve brake line should look like.

Thanks, Dave

No prop valve on a drum/drum system.

The proportioning is designed in via the wheel cylinder diameters, front vs rear.

The single line is plumbed into a distribution block.

Apologies - I don't seem to have an existing photo, and I can't take a photo because car is not here (it's in a museum in Flint).

Sorry -
