The "upgrade" brake line kit comes with the lines having a tunnel at the back of landing gear. I like the protection it affords the line and looks nice. The only thing is that as the line comes up the gear it terminates at a place that doesn't allow access to the fuselage. I consulted other build logs and referenced some photos I took while at Torrance. I opted for what Torrance did.
This required drilling an access hole that would be just below the floor boards of the rear seat. I also required removal of about 50mm of material from the back of each landing gear to allow the brake line to make the turn.
