Dual Master Cylinder brake lines?

Hey guys! Thanks for all the information!

I wonder if I did something good or maybe just wasted my time. You guys tell me.

Went to the local scrap yard today and found a 1970 Plymouth Valiant. Checked it out and it has a dual master cylinder. I asked the workers how much if I pull off the lines. The guys tells me if I pull them off I'll only have to pay $5. So for about an hour I pulled them off. What do you guys think? Will they work for me? I'll post up pictures up in a min. I know I still need a proportioning valve but this could be a good start right?
