Coil Spring and leaf spring markings
« on: October 31, 2019, 03:13:15 PM »
Hi all,

I'm looking for final finish detail of the original springs for my 66H along with paint stripes of any kind.  Any direction in description along with pictures would be appreciated.  I will be reusing my original front coil springs and bottom leafs for rears.

Thanks
Shawn

When do you estimate the car was finished at San Jose? And what are the dates on the leaf springs.

Coil springs will typically be a since red - the tone and tint of the red varied so that is why the questions

 Jeff, would greatly appreciate any spring paint marking information you may have on a mid October 65 San Jose built k code that became 6s281. Leaf date 237e5.
Thanks very much, Karl

These are 207 and 237 springs from a SJ GT car built late Sept. or early October, 1965.

As mentioned yesterday, if you are fortunate enough to have originals, always go by those.

On the leaf springs, by that time in production, I always see the yellow and green "stripes" rather than the "round" markings.

Below are restored examples of both. BTW, it is interesting to note that 6S933 originally had one style on one side and the other style on the other side.



Below are a few pictures of the original front coil springs on 6S1732. It's tough to see, but in addition to the white markings, there are also reddish brown markings.

Here is the information I received from Howard Pardee regarding build date.  I will post pictures of the coil springs showing white paint stripes (not sure if that's the only marking) and leaf spring date stamp later today.

"6S1816 would have been scheduled to be built the 5th or 6th of April 1966. The key word here is "scheduled". The actual date is not known. The actual production day could be affected by parts shortages or labor problems. Since the car was shipped to Hertz 4/26/66 and it only took about a day or two to ship from San Jose to Shelby American and it only took Shelby American about a day to convert the car into a GT350, I would say that the 5th or 6th is pretty close. The actual production day could be affected by parts shortages or labor problems at San Jose and, of course, Shelby American could have had the same problems."

6S1757 also has original leafs like Brant's photo in reply #4, one having stripes, the other daubs. Although certainly rare and NOT typical, it was seen that late in production (late March SJ).

There was a discussion about the white coil spring stripes on forum 1.0. Most springs did not have the white stripes, only red or reddish brown. IIRC the white stripes were some sort of specification variation identifier, something like a little stiffer, or softer than the norm.

rockhouse66 Posted a typical example from your date range (hitting it right on the exact date). This matches what I've typically found from the same - spray dots



Here is the information I received from Howard Pardee regarding build date.  I will post pictures of the coil springs showing white paint stripes (not sure if that's the only marking) and leaf spring date stamp later today.

As mentioned in the earlier (now gone thread) the white stripes are typically applied at a different time using a different method (sprayed) to indicate that the fell outside of the rating when tested. Workers would install two matching front springs  (with or without stripes) when it came time to build a vehicle. Examples of white stripe coils can be found in all applications and were not used to identify (in 66) the application

Spring dates are the best way to identify pattern since a set from one shipment could be mixed with an earlier or wait around in the rack and mixed with a later. So this makes it more specific if we have matching examples in the data base

Here are the pictures of the stamping on the rear leaf and coil paint stripe.  I also notices visible signs of black paint on the coil when removing the top insulators.  My assumptions is they are to be painted black then strips added.  I could not find any stripes other than what looks to be white on the bottom 4 coils of each.  Any samples of a finished restored coil available?

Here is a set of restored coil springs.

Please note that these were just put back exactly the way these particular springs were found. This particular set did not have the white markings.
