VIN?

So it is a 1970 Dart Swinger 340 made in Canada, nothing else can be decifered from the VIN, what else do you need?
There is more info on the fender tag... should be able to decode up until the sequence number each of these means something...LM23HOR

as previously stated the model, engine and build plant may be all that's in these letters.
What those letters mean.
