There are differences in other assemblies. IF A-body spindles, calipers, etc.., The OEM correct lines do appear to be fine initially, especially while on a lift, spindle lowered. At normal operating positions, Steered to end of travel should put a kink in them where the rubber meets the short metal tube at caliper end. This high pressure hose is constructed much like a radial tire ( steel wires inside ) so they will not survive kinks. It'll fail right there. Try to bend/reshape that metal tube and you'll probably crack it at the join to the square block where the banjo bolt goes.
