I just went out in the shop and took these pics.

It my panel album but there is two pics. One showing the brake line coming off the rail, going to the "connector" and the two lines coming out of connector going to each side....
the other pic is a close up of the right side showing the brake line going to the bango "connector" smile which is screwed into the back of the wheel cylinder. Hope this helps. Mine is a 52 and I am sure it was originally like this.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
