68 Shelby Adjustable front shocks

[Ls6 Ragtop]

Hi Matt,
The full part # is Z7ZD-18045-A. I googled the part # and it came up with a link to the SAAC that had a posting with the same part # of these shocks and the answers the poster received listed them as 68 Shelby for both GT350 and 500. It listed the original manufacturer as Gabriel for Autolite. I actually have 3 of these and 2 are identical with only the Autolite stamping with the part # as shown in the picture while the 3rd odd one has FOMOCO and the part # is the same Z7ZD-18045-A.
There is a T6KA stamped on the FOMOCO one and T6LE on the 2 Autolite ones. I was curious if this might be a date code. All 3 are also stamped Made In Canada.
Thanks, Chris
