Brake line routing guidance

[64chevmn]

I'm trying to install an In-line disc brake conversion kit in my 64 c10. The old lines I took out we're a total mess and are no help for a pattern. I think have have the lines that run behind the cross member to the passenger side front brake and along the frame rail to the rear brakes somewhat close, but I can't figure out how the lines that run up to the proportions valve go??? Can someone that has ran their lines lately point me in the right direction? I just have the lines kinda zip tied together until I know I have the routing somewhat close.
