I recently purchased a 1972 240z. It was resprayed 10 years ago and paint is real nice still. I have a few minor spots to touch up and spent 3 hours at a paint shop trying to find the code . I tried #115 which has the white interior for this exterior paint (mine has this, original) and it's not it. I spotted a few Datsuns online with the same blue but I don't know the code.

I don't know the code but this looks like a 240z that was for sale in the Corpus Christi area? Is this from that area or somewhere else? Just out of curiosity.

Just saw your post. It looks more like #903 on my monitor. Was #903 available for the '72 model year in the USA?
