There ARE places that make custom hoses. Masthead is a mobile version of that. Some NAPA shops might. You could have 1997 on the chassis end and 2017 on the caliper end. Remember the fittings on the ends are "clocked" so the hose installs and rests without a twist in it. Also, the E450 uses HydroBoost braking vs. vacuum boost on E350. I wondered why and found out that Hydro produces Many Times the brake apply pressure that Vac can supply. Multiple times more, so even more reason to make sure brake hoses are RIGHT.
