63 first design heater air duct
anybody got a picture of the first design heater air duct(fastens to the underside of the heater box just behind the radio). i believe its a two piece design as opposed to the mid63 to 67 one piece duct. btw, the mid 63 -67 , although assembled in one piece, actually cosists of a metal piece riveted to the fiberglass piece. i suspect the early 63 duct , although consisting of two seperate pieces, actually is composed of a large piece that is composed of a metal piece and a fiberglass piece, while its smaller section is composed entirely of fiberglass. thanks,mike

You don't mean the defroster diffuser, do you. Is 64xx early?https://MichiganNCRS.org

Re: 63 first design heater air duct
Mike, here is what I have.
The Y duct on the left was used on the later 63 heater box, the one with the circular mechanism. I have an inside box that is dated April 20, 1963 (new design). The piece needed to be removed in the Y duct to allow the circular mechanism to function.
The Snout on the right is the second design. I believe the shape was changed to accommodate the AC duct work under the dash. The second design works on non-AC as well as AC cars.
I have the one on the left on my non-AC car (April) and the one on the right on my AC car (July).

Re: 63 first design heater air duct
no, not the defroster duct that is located just under the speaker grill. i'm interested in the air duct that directs warm air to the driver and passenger feet/knees. it fastens to the underside of the heater box, unlike the defroster that hangs above the heater box. mikeComment

Re: 63 first design heater air duct
harry. thanks much. what i have is the Y shown in the right in your first picture and the smaller fiberglass piece on the right in your second picture. i can't figure out how the right #1 attaches to the right #2, if in fact they attach to one another. i removed these pieces from a 63 vin 10912 many years ago and forgot how they are utilized. can you provide further insight on how they are attached to the heater box or to one another? i believe the entire heater assemblies were supplied to the st louis line by the source, hence little help in the AIM. thanks,mikeComment

Re: 63 first design heater air duct
Mike, I can tell you that my 63 mid March car (110674) does not have the smaller down spout on the drivers box and has never seen it as there is no cut out. I think that there was a date the could be closer to my car when the down spout started. Harry might know more on this.New England chapter member, 63 Convert. 327/340- Chapter/Regional/national Top Flight, 72 coupe- chapter and regional Top Flight.Comment

Re: 63 first design heater air duct
If you are talking about the little "add on" duct on the left, I recall that 6422 looked like that. I could not find a photo, but know where the car is now. I am no longer the owner.https://MichiganNCRS.org

Re: 63 first design heater air duct
Not on that one as that is a picture I pirated. I just re-looked at my April car 13356. It has the old style box with the spring and lever mechanism.
A correction, my April car did have the snout with the extra angle for AC Cars. Meaning, that snout was changed with the introduction of the first production car built with AC, that was in March sometime as I recall.
Also, I would think based on the date inside a box (correction 4/29/63) I have with the circular mechanism, that the second style Y duct was introduced in Late April or early May.

Re: 63 first design heater air duct
Edward,
Your heater box should have a small rectangular cut out and the drivers side radio side panel should be cut out in that area to allow the snout to protrude out near the drivers foot area.
My early 63 has it, if you car does not is there a chance the heater box has been changed to a 64 up dated box as I believe they are the same except the new lower duct provided heat to the feet as well as out through the radio side panel hence no rectangular cut out where the snout would go.Comment

Re: 63 first design heater air duct
April last day car 14043 has the early style defroster mechanism hence the Y duct on the right with the corner intact. My records don't include a inner box inked date. Sorry. I believe it is right at the cusp of the change however.Comment

Re: 63 first design heater air duct
At the only National I attended, Novi 2011, I remember Carlton being interested in this 'snout' or at least the rectangular cutout above the Y-Duct. I think he checked each for the presence of the 'snout' or even a cutout. I am not aware of his learnings. I remember o/a there were two cars being judged there which were made the same day as mine, and one was a Z06.
This inner core change is a good example of fact that changes were not simple early to late but 'just a pile of parts' made the transition occur over a period of time. Harry's late inner heater box at 13356 and my 14043. I found the same to be true on the hood surround metal reinforcing bar behind the headlight opening ... same day builds have both early and late style. End of Apr 63 builds are very interesting, the tranny too!Comment

Re: 63 first design heater air duct
My 203XX July 24 63 car has the 2nd design Y duct and no snout or cutout for same. There is a scribed outline for the cutout however on the main box. Mikie, believe your ole blue Z06 car was built the same day. Have you checked it?
