383 A-Body Valve Covers Question

My dad bought a 67 gtx some time ago. It was an awesome barn find. All original. The right chrome valve cover has the bracket for the heater hoses. My 69 383 barracuda has the bracket on the inner fender for the heater hoses. Now my car came from my uncle who ordered it new & the chrome valve covers he gave me have the bracket on them & he swears they came off the barracuda. He doesn't remember how the hoses ran.
