Topic: 67 Rear Spring Markings Discussion

[J_Speegle]

No disrespect to Jeff, but of the 50+ 1967 Mustang build sheets I've seen, the C9, "HD Suspension" field

Kevin double checked my post (reply #39) and the C9 was simply a typo on my part and I've gone back and corrected that in that response

Sorry for any confusion

Though I've looked at over a dozen comp suspension cars none of them had with them a buildsheet. So as of right now can't answer how those were marked either

Been a while, but I was in a position to paint my rear leaf and went back to the best picture I have of my (Shelby) competition suspension rear leaf in order verify color.

I had to sand a little bit to get through the first layer of paint and I find a brighter color than first noted. It is definitely orange, albeit a bit more on the yellow side of things.
Pic attached.

Thanks for sharing - For others viewing the picture above is from a March 2 67 built Shelby with C7ZA-AR rear springs dated 040 E

Here is a picture of the bottom leaf out of the 67 Shelby GT350 we are working on.  One picture wet, the other dry after being derusted.  Definitely look orange when wet.  Build date 05/02/67.

I was trying hard to get to Brown (like the Paperback Writer's sheet says) but I think Orange is a better fit for what I found.

I did get from SAAC the SVO Parts Spec sheet for my block of Shelbys (280 of them) (schedule date of 2/6) and find that:
"Items to be deleted" is C7ZA-AA Spring and Bushing Assy - Rear
"Items to install" is C7ZA-AR Spring and Bushing Assy - Rear

On another front, Richard (67gtasanjose) wanted to know the spring code on my son's GTA fastback and here is some data on it from the 999 report:
7R02A149xxx
Date: 12/6/66
GT (incl heavy duty suspension)
XP automatic
Power Steering
Exterior decor
Styled wheels
No A/C

The spring code on the GTA  (it took over 2 dozen pics at various angles to find the code) is "AE". There is no way I could find a color on this extremely weathered spring.

I looked and didn't find the -AA mentioned in the list. It is in my SVO add/delete list as being deleted for Shelby use.
While looking through a swap meet table I actually found a set but what is the application?

I know it?s been a while, but was this subject resolved in this forum or another forum? I have a 1967 Mustang export car that has the D marked under the Handling package column and nothing marked for the HD column on the build sheet. It is a GT so am I to assume that it is simply referencing the GT special handling package only or did it have the competition handling package? Let me know. Thanks.

Sounds like, based on your report, that your car is marked as other non-export GT's were marked on their buildsheet

What are the  spring and shock letters?  That would help confirm also IMHO

Do you happen to know where your car was suppose to be shipped to and the DSO?  To help others

Hi Guys,
My Google search led me here.  Very hard to find much out there on leaf spring stampings.  I have a pair that came off of a 1970 H-code Mach I and was surprised to see a C7 part number.  This car had a rough life passing through several drag racers so I guess I shouldn't have been surprised to find something unusual.  I haven't been able to reference the stamped numbers anywhere:
C7ZAAT
252  88
I counted and I could swear they are five-leaf issues.  There are also faint yellow painted numbers on the topside right next to the eyes.  They were four digits, followed by a space or hyphen and two more numbers.  They were dim and I didn't want to rub them off, so maybe homework for me to decipher or photograph if important. Thanks for any help you can offer.

The spring codes are listed in the post 1 attachment.
It appears you have an AT spring listed for a 67 390 GT

[Asedan]

Thanks Bill.  I looked at that sheet and missed it somehow.

If your springs show evidence of a stenciled yellow part number that identifies them as replacements. Comparing your cars real build date and the date on the springs will likely confirm that

If so they are likely not the original markings (stamped engineering number on the short leaf) but simply what Ford carried at the time when they were replaced. Applications and all the variations were minimized to help reduce needed inventory over time. For best reference we would need to look at a 70 or early 71 MPC to see what may have been the original rear springs for your application. And of course, if available to unrestored examples equipped the same as your car.

I invite you to start a new thread in the 70 sections if you want to dive into a look as to what your springs would have been originally. Or we can split your post and the responses or just let it die at this point here

[Bossbill]

I was going to ask for a pic of both the small leaf stamping number and the yellow one, but I was on my tablet and virtual keyboards suck.

[Asedan]

Yes Jeff, let me go back to the shed to photograph the markings and make sure of an accurate leaf count.  I will take your advice and start a new 70 thread.
We met a number of years ago when you were examining a half-and-half 67 or 68 notch.  I think it was at COTA when the HTA bunch came.
Thanks for the wisdom,
dave

One more update before I try to post with photos.  These are 5 leaf springs with yellow stenciled 42-435 on top of the big spring.

As described is not a aseemblyline spring for your Mustang .
