Couldn't edit my previous post, gave up trying to upload photos here so put them in my photo gallery here.

My LOS 67 has the tank stamp.

5 D 7 (the D is reversed)

And a fairly complete  blue stamp or stencil that reads:

 12 19
51865
MADE IN (I'm assuming USA got lost over the side.)

Here's the current compilation.
67 has a calendar week code. 16 D 7 would be the 16th week of 67, day shift. 40 6N would be 40th week of 66, night shift.
The format changed in 68 and 69 to have the week counted from the beginning of the *model* year. The extended 69 model year used tanks dated for the 70 model year.
LOS and NOR data is intermixed and shows the same pattern.

67:
