I am working on this as well.  I decided to run lines up/over to the frame from each caliper to the frame.  From Summit I will be ordering 2 Russell Performance 657320 13" hoses banjo to female inverted flare.  I used a piece of hose from the caliper to the frame to determine the length.  I am actually only ordering 1 hose to test fit in case I need to return it.  I am also hoping that this hose will work up front or at least I can use it to determine the proper length.

For mounting tabs, I am ordering Helix Brake Line Mounting Tabs HEXBLT1 - these are weld-on tabs with clips.  There are some bolt on tabs that will also work depending on how you want to mount them.

On the driver's side I am going to run a short tube from the tab to an inverted flare "tee".  From the passenger's side I'm running a tube across somewhere above the rear end and safe from the drive shaft into the "tee".  From the "tee" I'll follow a somewhat stock path to the front of the car.  This way I don't have to mount any tabs to the rear end.  I think I read that some late model mustangs run their lines this way.   For many applications this also provides a little more room for exhaust.  I re-threaded a vent tube all the way and will mount it in with a copper washer to keep it sealed in a somewhat stock location.  My rear end was a custom built unit and I am going to have to move the vent tube hole since it is sitting right where I need to run exhaust through my coil over setup - par for the course.

All that said, you can run a 69 big V8 hose (maybe boss) from the stock frame location down to the axle and run tubes out to each end to terminate at tabs.  There are several V8 hoses for 69 and a few provide good exhaust clearance. You will still need flex lines and several stock hoses may work.  Russel performance also offers shorter hoses that will work well.

How much clearance do you have if the suspension bottoms out?  The exhaust pipe looks a little close but it could be the camera angle.  When I used the stock location on my 66, my exhaust guy said that he got the pipes to clear with no problem.  Apparently "no problem" means - until you hit a bump or go over a curb and drive the vent hose pipe into the exhaust pipe and break it off the axle.  The 69 big V8 style rolls the brake lines towards the front of the axle and away from the exhast pipes.

Rules of the road:
You must use a flex line between the caliper and the axle, or the caliper and the frame rail (like Garys') In my opinion, the Versailles hose works best as it has its own bracket.
If you use a center hose, use the 69 hose,  It clears pipes and shocks best.
Relocate the hard line on the body like a 69 Mustang.  It works great (pic attached but not real clear)



I now have ebrake cables for 65/66 to make it easier to modify and install the ebrake
