Heater Hose Inner Fender Routing - 71 Demon 340
I have a 69 BB 383 Fish that 99.5% had that similar mounting location.
A different Bracket I believe that turned up not down as pictured.
My car had never had that mount location punched on the inner fender or any where near it!
I agree with
@Dana67Dart, however even the manual is not accurate all the time!
Most 69 up to 70? were in that location and maybe different brackets were used!
