Some GM plants stamped the bell housing not all vin. stamps were in a mandatory spot and the whole vin# was not always stamped! and The plant, date, and engine ID codes were stamped at the respective engine assembly plants while the partial VINs (when applicable) were stamped at the final assembly plant. Therefore the two stampings will have different fonts, character sizes, and in some cases will be stamped at different locations on the engine block! I do remember that early on Vin stamps were not manditory it was volintary from plant to plant I don't remember when it became manditory
