I just removed my leaf springs, shocks, and axle housing from my Metuchen '69 R-Code Mach 1, and was wondering if the date codes are consistent with the March 4, 1969 build date of my car, and could be original to the car. I believe they are original, but I was told driveline components (incl differential) in '69 were very close to the build date. The date codes as follows (see pics):
Leaf Springs => C9ZA 5556G => 8B8
Shocks => C9 F 18180 => 9A8
Differential Housing => 9AD
Differential Tag => 9A7
Also, the differential tag indicates a traction lok, but the Marti Report does not show that as an option.
Thanks in advance.
