1970 Dodge Dart Swinger Disc Brake Swap Help Needed!

The alignment geometerty of the 2 spindles is the same so switching wont effect alignment
I know this wont sound right but... The calipers were mounted at the front or 11 o'clock position on 73 up models. That correct fluid hose was routed through behind the spindle and did not stretch or conflict with other parts.
When the calipers are mounted at the rear or 1 0'clock postion the fluid line could get stretched even though it's closer to the connecter point on the frame rail.
What I do is have the vehicle lifted so the knuckle drops as low as it can, then steer to end stop. Then I bend the steel tube portion of the fluid hose just enough to relieve the stretch. Dont allow it to bend at the square block end or it will crack. Dont bend it up so far that it hits the wheel.
Some say there is a longer hose found on F-body that works without the bending.
Hope this helps.
