I have the Marti report on my 69 GT500 which states the car was built on June 13. Was this the date that the car was built and delivered to A.O. Smith, OR was this the date the car was a completed unit and delivered to Shelby, or the date that the car was COMPLETED at Shelby? Is there a way to know when the car was completed from Shelby? I am asking to determine the if Shelby components (i.e. Carburetor, shocks, etc.) may have a later component build date than that shown on the Marti.
The dates on the Marti Report are Ford build dates. That would be the date the car was built/semi completed by Ford.
The dates that the car was completed by AO Smith would be later. You might be able to determine a window when the car was being built at AO Smith by finding a shipping date. That however, maybe much later than the cars actual completion date.
I can't think of any dated components were added by Smith that would be after the Ford build dates, unless you have a 1970 Shelby.
The carburetor would have already been present when completed by Ford and should precede your Marti report dates.
I believe in the case of 1969s, shocks were added at Smith, but its unlikely they would have such a tight window on date codes. Maybe someone who has studied that more closely will chime in.
Drivetrain parts on 69 gt500 installed at ford dearborn but shocks and leafsprings were installed at a o smith later.

That must mean there were takeoffs of the Ford parts?
Mr. Coralsnake. You just confused the heck out of me with that reply. There are no completion dates at Smith for the '69s?
I have not seen a list of Smith completion dates
Am I remembering correctly that Smith lost most if it's Shelby related files in a fire?
Could have sworn I read that in the Registry but can't find it.

Just looked at 69 shelby build sheet #1710 and the shock area color codes are blank and i would think the rear shocks were first installed when the s9ms rear leaf springs were installed at a o smith and the front shocks were installed using the unique welded washer shelby upper shock mount brackets also done at smith thats what i think anyway but not 100% sure and u can ship a car without shocks installed and less labor removing regular mustang shocks and reinstalling shelby shocks. I need to check an early 69 shelby with blue shocks buildsheet to see if it also has blank shock color codes. #1710 buildsheet had white shocks still on the car i just inspected 26.000 miles shelby.

Just for clarification Ed is referring to the Shelby unique C9ZX marked painted white shocks that were installed on 69/70 Shelby's built after approximately mid March of 69. The earlier 69 pre mid March 69 shocks although adjustable were marked Z7ZD and were not Shelby unique. The adjustable shocks (not Koni) that were used on 66,67,68 and earlier 69 Shelby's were typically installed on the Ford assemblyline as indicated on the build sheets/DSO sheets. The blank shock marked box on the later 69/70 build sheets (after mid March) would support Ed's AO Smith added point of view for those specific shocks IMO.
How do you ship a car without rear springs?
You dont.
Smith replaced them

What is the difference with the shelby spring? Does it have a different arch?

Different leaves and in turn believe different load ratio.
Bottom short leaf is flat and has c9zx or s9ms #s and only use 2 wraps not 3 like other rear springs
If you compare the separate leaves of the 69/70 Shelby leaf spring you will find that the only one that is comparable to a regular Mustang is the main leaf with the front spring bushing . The others are different longer lengths . The bottom leaf is flat as Ed described. Many 69/70 Shelby owners don't realize that they are so unique and replace just the bottom leaf thinking that is the only difference. Wrong.
I've know that the 69 springs were Shelby unique for quite a while. I just presumed that they would have been installed at the Ford assembly plant as done in previous years for "Shelby units"?
Plus it's good to raise questions like this here to call attention to these special situations so that the newbies deal with a steep learning curve quickly? ;D
In previous years the rear leafs were ones also available on regular Mustangs. Those were installed on the Ford Assemblyline. Not so for 69/70 Shelby which were unique. I have a extra set of 69/70 Shelby rear leafs and a set of BOSS 302 leafs setting side by side. although the Boss leafs are special as indicated by the engineering number on the bottom plate they are the same dimension as regular Mustang. I took the picture to show difference in all of the leafs except the one with the front eye bushing.
Also the 2 spring wraps had round holes vs 3 square hole wraps on regular ford mustang springs. The very early 69 shelbys had a different spring and different id #s not s9ms or c9zx.
Does anyone have a list of what parts were changed over once the car left the Ford build plant? Both at A.O. Smith and at Shelby. And does this vary by year? I am working on a 69 GT500 (Dearborn built) and would like the information as it pertains to my car, but I am sure that it would help others too. EXAMPLE; On my Carb, it is a 9510 AND has the Shelby specific 4280 list. Where and when was this put on the car? And with the carb, if put on at Ford, since there were so few Shelby's built, what would I expect for a build date on the carb?
What was the reason for the change of springs? Did they REALLY make a big enough difference in ride or handling to justify the labor and part cost. The bean counters must have been jumping up and down over this!

The semi-completed cars were running and driving cars when they left the FORD plant. Your carburetor was installed by FORD.
Those cars were transported to AOSmith for completion into 1969 Shelbys. If you look at the production photos, you can see what was added.

These Shelby unique parts include the complete front clip, all other fiberglass components, wiring, roll bar and Shelby console. I might suggest purchasing the Shelby unique parts list for reference as to what these parts are.

The cars were not shipped to "Shelby". AOSmith was the contractor used to finish the cars. Shelby was responsible for management and quality control. Yes, the parts that were changed and or modified varies by year.
QuoteI have the Marti report on my 69 GT500 which states the car was built on June 13.
If you have a C9AF-9510-N /Holley list 4280 it should be on a GT500 automatic. It would very likely be dated within a six period before your car was built by Ford. In your specific example, I would expect one of these date codes: "951/952/953/954/961"
I dont believe that carburetor is Shelby unique.

The C9AF-9510-N carb is not Shelby unique. What would make it unique was when for 1970 Shelby it was modified (ED for edited on tag)by Kar Kraft with a manual choke .
