As it turns out, you will need only the Dual Master Cylinder and a couple of small fittings!
1 Remove line going into front of old M/C and remove old master.
2 Carefully remove push rod, install in the new M/C and mount on firewall.
3 Bend the line that was in the front of the old master and run it into the back of new M/C (large res.) = Front Brakes
4 The line coming from the rear brake goes into the current dist. block...
5 Remove this line and get a 3/16" double flare fitting and plug that spot on the dist. block...
6 Bend the rear line to run into the front of the new M/C (small res) = Rear Brakes
7 This will require a 3/8" to 3/16" fitting for the rear brake line to enter the new master....
8 Fill with brake fluid and bleed...
PS If you want to run a Proportioning Valve, your run it in line of the rear brake line and in this case, you will need a small piece of brake line 6-8" . Do not use any teflon tape, you will strip it...
