Need Some Pics for Disc Brake Conversion

I am working on a 66 Mustang 289 manual drum to manual disc brake conversion. I'm using a stock disc brake master cylinder for a 66. Can anyone provide some finished pictures of how you did your plumbing from the master cylinder to the proportioning valve and also to the brake distribution block? Thanks in advance.
 
I don't have any pix, but I can tell you the basics in words. First, I started with a '65 with 4 wheel drums and a single circuit MC.

With the dual circuit MC, the reservoir closest to the firewall is for the front brakes. You've got to split that line, to go to the right and the left. My '65's factory setup used a T-block with no internal valving, to split between the left front, right front, and a single line to the rear. I bent a line to go from the rear reservoir to this T-block. I just plugged the rear system's port with a pipe plug, and left the factory lines to the LF and RF in place.

My kit came with an adjustable prop valve for the rears. You understand that these adjustable prop valves can only reduce pressure to the rears; they have nothing to do with the fronts. You set the prop valve so that the front lock up first, slightly ahead of the rears. So anyway, I bent a line to go to the front port of the MC to the prop valve, then bent the factory rear circuit line to mate to the prop valve, mounted on the inner fender. I'm redoing the system now, and I will probably put the prop valve in a more accessible spot.

That's a lot of words to explain some pretty simple stuff, but still it's fewer than one thousand, yet probably as good as a single picture.
