I am forming and putting new brake lines onto my convertible. The old ones are long gone and I am unsure how to route the line once I reach the end of the front subframe. There does not seem to be any pictures that I can find. If you have any pictures of how your rear brake line is routed it would be appreciated if you could share them with me.

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.
