LA and Norwood VINs are not identical by date they are sequential by assembly plant. That is, there is (or could be) a 9L512345 and a 9N512345, of course one could be a 6 cylinder convertible and the other could be an L89 coupe. Also LA stopped building cars in April of 69 due to a GM strike at the Van Nuys plant. They came back on line in June to finish roughly 1000 cars that were actually on the line when the strike hit. There are no build dates later than 05A from LA in 1969.

This car is an early build, with a bunch of incorrect parts, at least the engine, rear axle and cowl induction hood which wasn't available until the first week of January of 69 (Yes the first ZL1 built during the last week of December 1968 has a cowl hood, but that isn't exactly a production car). Does this mean it is or isn't a Z28, I don't know but someone would have to prove it to me if they wanted my money.
