Sorry if this is a hijack but I found this kind of interesting. I saved this Protect-o-plate from a junked out '72 Blazer with delivery date of 5/23/72.
V1116TDB is the engine- V: Flint, Mi, 1116: Nov 16, TDB: 307
RAWW321 is the rear axle code- 3.73's RAW: 3.73, W-Warren, 321- 321 day of the year.
N2S12 is the trans code- SM465 4 speed
and it looks like the little bowtie next to the 'K' may mean it was a Chevy K-series (4x4).
Not sure what the single 'B' is for.
