1977 SWB 454 A/C Question
 

Does anyone know where I can get the A/C control vacuum hoses that feeds all the vacuum to everything for the controls off the selector valve. I'm restoring truck ground up and found vacuum lines have been melted in the past. ( EXPLAINS WHY IT QUIT WORKING RIGHT ). Looking for new,but would purchase a used one in good shape. THANKS GUYS IN ADVANCE !
