Help with brake lines

[Flysocal]

I'm going to build my first set of brake lines for my truck. wilwood discs all the way around. 1-1/8 bore wilwood master with proportion valve (haven't bought yet). 9" dual diaphragm booster mounted on the firewall. Never done this before and am wondering if anyone knows of a build thread showing details on this. Need to figure out design and will buy a good flaring tool.

I've got the wilwood braided adapter kit for the front I routed that to come through inner fender about as high as the valve covers. I see it's usually anchored to frame so I might have to rethink.

For the rear I'm thinking all hard lines but I'm not sure on design or routing. Any insight appreciated.
