I'm in the process of obtaining all the parts to swap my 9 in drums on my 65 Dart to 73-76 discs. In order to use my sway bar I understand that I can swap the knuickles from side to side. What brakes hoses should be used in this set-up?

You can probably use brake hoses for the 73-76 setup.

This setup have been covered before, you need to use f-body brake hoses. You may also need to extend the hardlines towards the rear so the rubber hoses are not over extended nor pinched. Another gotcha on this setup is that you need to make sure the bleeder valves are at the top. Otherwise the system becomes almost impossible to bleed.
