I’ve seen the small L before, but it was closer to the 7 with the space between it and the vin derivative.

The font is correct for some LOS cars and sometimes the spacing is not consistent. Also some LOS cars have 7L on the pad and others have L7 and then the VIN.

Thanks. Above pic is a very early / low VIN, so before the green car. Maybe LOS plant changed the L stamp in between the green car and my car. Or maybe two different stamp sets on two different engine dress lines?

That stamp on the green car is legit.

It's not an early vs late thing. Yes, I believe there was more than one set of engine stamps for the VIN at the LOS plant.
