Rear Vent Question
I have a 1974 Corvette Coupe (late production) non a/c car and was wondering if the rear deck lid vents are suppose to be cut out with the vent parts. I have found 74 coupes with them cut out and all the parts from the earlier years and others are just blocked. I was wondering if this was something they stopped doing in the muddle of the production year.
thanks....
thanks....

The 74 parts car I had did not have the vents cut out. The grills were just attached to the top.
I have heard of a lot of other 74 models that were either way. I am sure some other 74 owners will respond also.

Thanks for the info, was your parts car one with a/c or without? I had heard that this could determine if they had them or not.
thanks again

Per the NCRS Judging Guide:
On non-A/C cars, these grilles function to evacuate inside air to the outside as part of the "Astro-Ventilation" system. In A/C cars they are blocked off...The block-off plates are visable through the grills.
