66 Single to Dual MC Plumbing Question

Hi all--

I've been doing some reading on the (suicide) single to double Master Cylinder setup. I have a few questions before I attempt this.

I have a double MC already that should drop right in. I have one line that comes to a T and splits--I assume this is the front discs. I have one line that comes to an adjustable proportioning valve and then dissappears down the firewall under the car. I going out on a limb here and assuming that is the rear line!

My question is on plumbing. Will I keep the proportioning valve? All I should need to do is remove the old MC, bench bleed the new one, bolt it in and bend two new pieces of line--one to the T and one to the proportioning valve? Correct? I've heard some people say I need an adjustable push rod for the pedal and some say I don't.

How hard is it to bend and flare the line? I have no problems buying tools, so that is fine with me!

I may not have learned much, but I finally learned to A) ask questions before you take it off and that B) things that seem easy rarely are.

Thanks all!

What about the adjustable push rod for the brake pedal? Necessary or not?
