You have a truck that someone converted and short cutted the brake lines. The lines for the back of the crossmember go to the drums. 71/72 come across the front for the disks. I can send you pics if you want to see what it should look like with disks. You may have other issues that should be corrected in the braking plumbing.

Ok, so what would be the proper brake hoses to run if doing a conversion on a 70 and earlier with the brake lines on the rear of the crossmember?

Use all the 71/72 lines to include the ones running up to the master cylinder. If you use the 70 lines it can stress the rubber hose running to the caliper. Seen it, corrected it.

Also, the prop/combo valve is different between 70/71. I changed mine out.

EDIT: Master cylinder as well is different. I also get the new rear line that comes with the front set. It will fit into the brass union that runs down the frame for the rear brakes. You don't have to replace all the rear lines. Just loosen the clamps, let is slide and it will all connect, tighten the clamps back up.
