I recently purchased a 56 F100 that has been completely restored/rebuilt. It has an in dash AC system with heat incorporated but there is no name or model number on the unit that I can find and I have been unable to get in touch with the previous owner/builder. There is a valve in the passenger side kick panel with the control on the bottom of the dash for changing from AC to heat. Does anyone recognize this system by chance based on these photos? I have looked at Vintage Air systems but did not see one that has a similar setup. Any help would be appreciated. fficeffice" /><O></O> <O></O> <O></O> <O></O>
