i also use pushlock lines and fittings. All the fittings are drilled/tapped on the bottom side of my rbc. However, i think id be careful with which line you use with the pushlocks. I had some cheap black line, and when i stored the car i noticed it became very flimsy (maybe the heat?). I could literally pinch the line with 2 fingers completly closed. Maybe this is part of my creep issue.
