Were there two different air cleaner service decals used in 68?
Here are pictures of two unrestored 68s that have different decals.
-
I think either of those might be original and correct depending on the assembly plant and date of build. Ford had a generic air cleaner decal with the Autolite and spark trademark, there were also air cleaner decals that were specific to each air cleaner part number and replacement filter part number which would vary by engine size. I suspect the generic ones were early in the 1968 model year.

Yes Marty there were two versions used at all three plants during 68 production. Agree with Royce that the exact change over date is likely a soft one and slightly different depending on plant and even engine option. But in general I think we can narrow down the change to a fairly short window. Best we can do without being there and without having all the real build dates of cars we use as examples
Though most unrestored cars only have the adhesive remnants of the paper based sticker we have a few that are still legible that I was able to find. Invite others with original examples to add to the discussion or at least data points
Let me offer the following after looking through what I have available
Looking at just small blocks I found the latest vehicle I have pictures of with the early version of the sticker was 8T03J1186xx (approx mid Nov 67 build date)
(http://www.concoursmustang.com/forum/gallery/10/6-210718161546.jpeg)
The earliest example with the later version of the sticker (element part number listed) as 8R01C1426xx (approx mid Feb 68 build date)
(http://www.concoursmustang.com/forum/gallery/10/6-210718161652.jpeg)
Now if we step back and look at other engines we have original pictures from 68 with one of the famous 135 cars (68 Dearborn built 428 CJ cars used in the initial drag program) with the early version of the sticker. So this would give that car an approx end of Dec 67/first of Jan 68 build date.
(http://www.concoursmustang.com/forum/gallery/10/6-210718161800.jpeg)
So it appears that a general range could be suggested that the change over was in Jan-Feb 68
Hope this helps

Guess we should ask Marty where the two cars he posted fit in to my time line of my earlier post (VINs and projected build dates)
++++++++++++++++++++++++++++++++++++++++++
Royce might be able to associate a possible build date or VIN for this car with the early version

That particular car was painted red later when Dyno raced it, or I should say attempted to race it at the Indy Nats in '68. He was disqualified over a disagreement about the weight of the car due to erroneous information from Mercury sent to NHRA.
I seem to recall the car was a May or June '68 build, so well after the change of stickers. It has not surfaced to date so far as we know.

Thanks Royce. Seems odd that they would have given the car to them to use so late in the production year. Oh who know why at this point.
Don't want to get off topic so won't mention a few other things we could discuss in that picture ::)
-
Thanks for the help.
Sadly when I took those pictures I did not get the door tag information. There was nothing left on my cars but the glue.

Will drop this picture here too.
NOS air cleaner base, box dated 7/26/69.
C8OZ-9600-B - Should be 1968 S code GT, with round air valve on the side.
Decal C8OF-9600-C - specifies filter FA-41.

Adding this here from the unrestored June 68 San Jose built Mustang I have here
289-2V with a C4 automatic.

Can I suggest that posts include, where possible, the application for the air cleaner be included in the post. Might come in handy at some point for someones research. Hard to have too much details as we've found but a pain if we don't ahve enough to the point of where some has to be ignored somewhat without enough information about the finding and documentation.

The black 1968 XR-7 428CJ 8F93R589867 (scheduled build date 26U, actual unknown) automatic raced by Don Nicholson has been found since the original post was made. It turns out the red 1968 Cougar 428CJ (VIN not revealed) raced by Don is a different car. That car has also been identified and is known to exist also. The red car is a standard Cougar with 4 speed, a very rare combination.

Ok...good idea Jeff. I updated my original post with that information.

Jeff- The grainy picture you posted of a 135 air cleaner- was it from the March Hot Rod Mag? You can see the left 1/3 of the decal- I have looked everywhere for it to no avail. The base of the air cleaner for those 50 135 cars was actually from a 1967 Thunderbird. There were a number of variations in the air cleaner from the 68 1/2 cobra jets.
-
The earlier style decal with the Autolite star have seen on Krs at least into June That would seem to line up with Royce?s red cougar. Common denominator is 428 cj. Interesting enough is there is a build sheet change in early May from a -A to a -C. It seems both have star decal. Although the info indicates entire air cleaner assembly the only noticeable difference is the filter FA 50 to FA 41
-
The problem I think is that the stickers were placed on the filter housing. Then at some point the filter housings were installed at the vehicle assembly plant. No one likely cared whether a filter housing was the first one in or last one out.

Royce I tend to believe that the stickers were placed on the air filter base and top at a substation at the car assembly plants. Stickers came from one provider while the other parts from another suppliers. If I recall correctly in a number of the different year assembly manuals there are instructions for the location of the stickers and that suggest to me that they were one there or they would not have been part of the instructions as to how Ford wanted the cars to be assembled at the car plant. Little difference but this could, of course explain some of the somewhat random pattern we find since we've yet to consider where each of the findings came from (car plants) They didn't have allot of storage at the car plants and the stickers take up little room and could possibly get mixed up, based on when they were received maybe a little easier. Of course considering that we've included NJ examples it's always seems to appear that there could be less care taken at that plant when compared to the others.
Just possibly a consideration

I am just trying to understand how a very late built Dearborn 428CJ Cougar could have a blue painted air cleaner top and the decal from very early in the model year. Both were supposed to have been phased out by the time that car was built.

Wonder when the picture was taken (new fresh car or something that had been run by him for a while). You know racers and details count while other details don't but good question. Didn't look it up but do we know the VIN and build date of that particular car? Guess this is a subject for a deep look for another thread about the lid. Is the flapper section suppose to be blue on a Cougar?

Guess your referring to the B&W picture at the bottom of Teply #2. Sorry not enough room in the title field for labeling the picture to show everything. Don't believe I originally scanned this picture so don't recall the source. If that is a 67 390 base then they had the use the snorkel style from the thermactor 390 cars as a beginning point considering there are no cut outs for the dual screens and it has the front elbow for the breather.

The car is VIN # 8F93R589867 and had a scheduled build date of 26U as I posted in post #10. The air cleaner lid was changed to black around a month earlier on all cars, including Mustangs and Cougars. So this air cleaner assembly was existing and old when it became part of that car.
