The photo of the underside of my '73 hood with the "Competition" vent matches what Carl's diagram shows. Unfortunately, the dealer's paint didn't hold up as well as the factory's.

Hi Pat:

The Datsun Dealership that I worked at in 73 put the competition hood vents on only 2 out of several hundred 73 240Z's. It is a very rare Dealer modification to say the least. Yours is the first one done by a Dealer - that I've seen in the past couple decades. Must be a very low mileage example - Yes/No?

FWIW,

Carl B.

Carl,

I bought the car in Texas in 1979 with 43,000 on it. It's now at 123,000. So not so low mileage, but not too high either. I agree it must be rare, as other old time Z'buffs tell me they have only seen one or two others.

Maby the same guy that did the Foam Car........................
