Does any body know what a good length and what size of fitting to buy when you do a disc conversion using the newer aluminum m/c and a proprtioning valve from a 74 dart..

all brake lines on mopars are 3/16". the fitting that go in the master are the same as 67-later styles. i know they take a 9/16" line wrench.
