Brake line routing for a '71 Disc

[OLDIRON69]

Yes, I searched and searched some more...

My truck is a '69 and I have swapped everything suspension wise to '71 specs. I would have just swapped the crosmember but everything needed replaced or rebuilt so I went the long way around....

I ordered pre-bent brake lines and I could really use a diagram so I don't screw something up. I have a new disc/drum prop. valve and master cylinder, all new brake compnents...now just need to get some juice to them...HELP!!!

One more Q- The bracket that holds the flex line, can I cut it off and weld it up front or do I need one from a '71? I did gather that the hard line runs up front, but being pre-bent,,I tried that with no real luck.
