Yes I just have one of the AU springs
Here are some pictures The orange/ pink AU are on the 68 J code GT HCS coupe. You can see this pair was side by side when marked.

I had been researching the springs I had on hand, I was pretty sure the fronts were original and the rears were not. The front coil springs were confirmed because of information shared in this thread. They DO HAVE the the violet & orange markings.

The REAR springs have been the last issue to resolve. I cannot un-do the decision years ago to replace them if I do not understand what was at least INTENDED to be there....
It would be nicer to find ones date correct, confirmed through similar build info and with codes that can be confirmed through the charts provided within this thread as 665lb.? load ratings (codes: AS, AT, AU, AV).

Regarding the front Springs, I have those restored and ready to go back in when the car is ready. It sure is nice confirming the original front springs under the car, and the car being from Southern California... essentially, rust - free. A quick dip in Rust 911 rust remover and I wipe down with a little oil and they are ready to go back in! Orange & Violet paint daubs are the originals and look very nice without touching up!

NOW, if anyone can help me find some Sept. '66 thru mid October rear GT lower springs, I could be set! (-AS -AT -AU or -AV seem to be good candidates)

Would GTA fastback codes be at all helpful?

Are these coming from an original example or from a buildsheet?

Depends. For fronts its likely that they would be different

If for rear then it would need to match the time period options and engine type. Of course if these are coming from an original example engineering numbers would tell us if they were the same

The info might be of help with Bob and his spreadsheet project in the other thread. Could always PM him directly

The car was my daily driver in the 1990s and is now owned by my son. It is a 7R02A149xxx GTA Fastback (w/GT equipment group),...
...It makes me want to run a Marti on this car!
http://www.concoursmustang.com/forum/index.php?topic=16751.15

Assuming the fastback GTA you mention is the same car you speak of in the other thread (on dual exhaust), it is a bit later build...quite possibly using different -suffix codes than my example would have come with. Regardless, fitment/function-wise, they would be the same. Concours-wise, not as likely given the investigation and findings we have done to this date (Feb. 2018). I believe the date stampings combined with the suffix's of such original examples are the key.
In any event, as Jeff mentioned, it would be helpful to get the date code and suffix codes from those springs. Even better if you had the Marti report to add actual build date to perhaps only a scheduled build date (using data plate and/or vin# as our only clue of the car's date).

For reference only in this comment, consecutive number of my build is mid-127XXX (earlier than the 149XXX I assume is your son's car)

On a seperate thought, I seriously wonder (speculate) if the running changes mentioned in the MPC's (shown earlier within this thread), had anything to do with the tire clearance issue they were having with the Wide Oval tires. Just spit-balling an answer as to "why a running change" on the springs.

I found the spring code on 7R01C189340 (no a/c, C4, not a GT) and it's a -Y.

Base model coupe, what I would now expect to find. Now if we could look at that December built GTA fastback...

Since mine is an SJ car, as expected, no build sheet, so no code.  But I did uncover Yellow Violet color as stated in reply #4.  Also with detailed pictures in a post that is a couple years old now, my how time flies:

You have the words 'action=post' in the url you list.
That won't work.

Ruppstang, do you still have the AU Spring? Please let me know. Thanks.
