Hi all!

I've had my dual master cylinder mounted for a few months now and finally got ready to go buy brake lines, when I realized I had a problem! My dual master cylinder, that I bought to replace the original, has 4 ports!

I bought this one, apparently by accident: http://www.americanclassic.com/images/BR0129.jpg

It says it's a "1936-1991 Master cylinder, dual reservoir, 1 inch bore, two 3/8 inch ports on each side (total of 4 ports), has deep bore with metal insert for both manual and power applications".

My truck has 4 drum brakes and no prop valve. Am I out of luck? I was considering running a line out of each port, directly to each wheel because I've read that drum cylinder's are metered at the port and don't use a prop valve but I have no idea about brake systems and why that would / wouldn't work.

I've goggled a bunch of various terms but can't find a solution. I'd really prefer not to have to order another one if possible. Any ideas?
