Dual reservoir master cylinder upgrade

Has anyone upgraded from the single reservoir master to a dual res. master on an early model A-body? I have a '65 Barracuda & I just got a kit off ebay with the new master, fitting kit & an adjustable proportioning valve. I am having some trouble following the instructions & was looking for some first hand help, advice, pointers, tips, whatever. Any help at all would be greatly appreciated. I understand how important this upgrade is but it seems beyond my abilities & I have been working on cars for over 20 years. Do I even need an adjustable proportioning valve? Where should I mount it? How should I plumb it? How do you adjust them, never used one before? Are there any surprises or tricks I should know about? Any advice on tubing lengths needed, parts to buy? Thanks
