I would check some of your local garages or parts houses that have garages. Some guys still make custom hoses and they shouldnt cost ya any extra change over an OEM hose. We have a local guy here who will make any thing ya need. Also check some of the hose types the MII big brake (GM calipers) conversion guys use. They have a 16" I'm sure I remember reading that meets your app. Sorry couldn't give ya a direct part #.
