F1/F47 Defroster Hose

[100550dvr]

Forgot to ask this question in my last post: how are the two defroster hoses secured in an F1 or F47 pickup truck? These hoses were missing when I purchased my restoration project. Is there some type of clamping device? I have what I consider to be the most authentic hoses that I can source for this project.


Looked in my service manual and cannot find an answer.


Thanks for your help.
