1970 Dodge Dart Swinger Disc Brake Swap Help Needed!

The hose routing works better if the calipers are mounted ahead of the spindles. If you insist on mounting the calipers to the rear then what you want to get are the late model FMJ calipers that were designed to be rear mounted. Then get a set of custom brake hoses and you'll be in good shape. Any other setup is most likely a hack job based on what I've seen.
