Title: Types of non A/C heater box?
Post by: Kyle Zammit on September 03, 2023, 06:35:38 PM

Hi all,

I have a question about the heater box types for non A/C 67 Mustang. I am seeing that there are few types of boxes marked FOMOCO in oval or FOMOCO in rectangle or no FOMOCO mark and different fiberglass texture. Is this was a vendor type or date a change ? Any information please?

Thanks Kyle.

Pictures would be helpful. The 68 case is a different design.

Kyle. I?ve never noticed the logos before but I have a bunch of boxes with dates stamped that I can check. Do your boxes still have dates stamped ? If not probably restored. I believe only one vendor so different textures might be different restoration techniques

Here is what I have. The Y6M19 has no FOMOCO mark and the Y6L18 has FOMOCO in Oval mark.
No they never been restored. They have the Original Date ink stamps as well.

Where are you getting these heater boxes from? Did one come off your current car? Did you get a big box of parts and are trying to ID the application? You asked a similar question on screws for the instrument cluster. I'm asking as I wonder what is your ultimate goal?

I only have two non A/C heater boxes. The picture that is showing the FOMOCO in rectangle is not mine. I am just trying to know why there are the types of Fomoco logo's and types of texture? It was a date change or a vendor type?

Here's part of an answer. If you look at the attached page of "Ford Car Parts" (aka MPC - it says "Ford Car Parts" on top of every page), 1975 edition, section 184, page 12 (available in this forums library), the first entry on that page shows the service replacement stock number for the front half of the heater box, the half where the motor attaches, as being a 1960 Falcon originally designed part - C0DZ-18A542-A, and the rear half as being a 1967 Mustang originally designed part - C7ZZ-18A543-A, the half with the "door". (Note: The heater door was changed in 1967 to clear the lower RH edge of the dash, but it will work on 64 thru 66.) As FOMOCO in a rectangle was an early logo, replaced by FOMOCO in an oval, it is possible to get a mix of logos - it's possible.
