Anyone have the Nissan part number for the non-vented pillar emblems?

did you find out how he got the car before it was made?

From my 1972 Fairlady Z parts catalog, models including S30, HS30, and PS30:

76807-E4100 Ornament rear quarter RH

76808-E4100 Ornament rear quarter LH

The E4100 indicates the initial or "earliest" application however I don't see why there would be a distinction between left and right hand installation if it was not vented?

A later part number E8200 is listed with a specification of "from chassis # S30-04551 and PS30-00401".

They are asymmetric, as they have to fit to a subtly double curved surface. I have a couple here on my desk and the rear surface (where it meets the body of the car) is slightly curved, and more so in one quarter. The emblems are market 'L' and 'R' on the reverse, with an arrow indicating 'up'. You can't fit an 'L' marked emblem to the 'R' side of the body (and vice versa) without ending up with a gap...
