blew rear brake line.

Trying to be "cool Dad" today, riding the teenage daughter and her friend in the convertible, some little demon on my shoulder told me to do a brake stand, I knew right away what just happened, blew out the rear brake line, the line that runs from the junction block below the master cylinder, along the frame to the rear brake hose.

Anybody know what size line I need to buy to replace it?

 

It may be 1/4", my 71 was....

 

you were correct, thanks. rear is 1/4" and front is 3/16"

 

It's 1/4" from the junction block to the rear brake hose. 3/16" to the wheel cylinders.
