'68 L35 4-Leaf Rear Springs

[Camarocards]

I need to replace the rear leaf springs on my '68 SS L35, M40, non AC car since two of the springs are broken on both the passenger and drivers side. The springs are original to the car and of the 4-leaf design. After cleaning the springs I uncovered the markings in the picture below. Can anyone decipher what spring code the markings may designate?

I understand that it was possible for a '68 L35 to have either a 4 or 5 leaf design according to the CRG:

"Generally, Z28's used 4-leaf springs and the other multi-leaf spring applications used 5-leaf springs. However, the use of 4-leaf springs was not limited to just 68-69 Z28's. Spring selection was a function of weight and options - and this was fine-tuned in 1969. SS, LM1, L65, and COPO cars with 4-leaf springs are possible according to factory documentation and they have been observed on original SS, LM1, and L65 cars."

HBC sells a 4-leaf spring and from what I've read, are nearly dead ringers for the originals, although they do state that the 4 leaf springs were typically used on the Z/28 or G31 suspension:(http://www.heartbeatcitycamaro.com/store/product/16815/Camaro-Leaf-springs-4-leaf-correct-1968-1969/)

I realize that there were many different leaf springs used in '68 but I want to make sure that the car sits at the right height and handles correctly. So before I plunk down $450, was it unusual for a '68 SS L35 to have the 4-leaf and not the 5-leaf design? Has anyone purchased these springs for use in a '68 SS L35 and can share their thoughts on fit, function and appearance?

Thanks,

Read THIS, and yes, there are a few (like mine) with 4 leaf springs out there.

Ed,

Thanks for the quick reply and link. It was a good read.

It's also good to know that there are other BB SS cars with the 4-leaf setup. I thought mine might have been the oddball but I guess it all depends on what was originally installed on the car.
