I have a 56 F100 that did not come with a heater. I'm in the process of mounting the control panel, and would like to know exactly where it mounts under the dash. I have sourced all the heater component's, and due to cable length, I'd like to be bang on, on this. Thanks.

 

Not sure how "bang on" this installation was, but this is the way it was done on my 56 when I first bought it.

 

Thanks Charlie. That's Bang On to me! Thanks for the pic.

 

That's where they were on both mine and the one I scraped..

 

There's pilot hole's for mounting, but I wanted to make sure. Thanks guy's.
