Brake hose from master cylinder to hardlines?

[Tom1878]

First time poster, long time stalker lol. I have a 68C10 SWB that I'm installing power brakes and front disk brakes and I'm wondering if anyone has run a stainless braided brake hose from the master cylinder down to the hard lines on the crossmember? I know the rear line is 1/4" but wonder how much the short 3/16" ID brake hose would effect the rear drums or if it even would? I can make brake hoses here at work so I can make whatever I need, just looking for some input from people who have possibly done it.

Thanks, Tom
