Help Build date junkies. Build date difference between car and transmission

Build date difference between my car and it's transmission.
This is my 1968 Barracuda

My car was build on Sep 26 1967 (926)
Transmission says it's build date is July 19 1967 (2182)

These just seam too far apart but Transmission does have the vin stamped in it. Since this is a early build car is it possible to have a transmission that far back in the calendar?
