A Body Disc Brake Swap 101

I have done the swap on B-bodys before, but this is my first A-body swap. I am lucky, as I have a 74 Duster I am swaping from. I have everything installed. I moved the dist block from the duster and spindels and upper arms. However. the sway bar on this car is after market so I had to mount the cal to the rear. Done this on B-bodys. But on the B-body conversion. I had to use a flex line off of a diplomat or something (cant remember) What is the best line to use on this type of swap. The port on the cal is now closer to the hard mount point for the hard line. and you dont want to crimp or rub the line on the tire or any part of the front end. Any Ideas?
