Brake lines for disk/drum prop valve?

[jimmydean]

So I have the prop valve and the lines that run from the M/C to the valve. But the stock lines are 3/8 and mount to the bottom, where the new valve has one on the bottom (and it's 1/4") and one in the back. I have been to every parts store and nobody has a 3/8 to 1/4" reducer, or a male to male union so I can run a short line to the back.

Where can I get these parts? Did anyone else have these issues when swapping the front to discs? Man, what a pain!
