This, from Yellowbird's site may help. Brake Lines

I took a few pictures when I replaced mine last year on my '68. I don't know how detailed they are but if you want, I can post some tomorrow.

I used Inline Tube pre-formed lines which made it a lot less work.

Edit: I found the photos. Note that the factory original lines in these photos were already disconnected from many of the clips but still in place when I thought that I better get some shots of the original in case I needed them to reinstall the new line.
That rear flex line to main line connector was obviously the source of one of my brake issues.
