That could be the latest version of the 70 GS Grill that general motors made it's black plastic Or a re-pop earlier ones were made with light gray plastic.here's pictures of a dirty NOS GS Grill I have to clean it up.
The light gray NOS Grill that came out of that box was $90. I bought the grill before I found my stage one I was going to build a clone.
GM got LAZY in the last runs of the 70 grilles. Original grilles were grey plastic Nos replacement grilles were black plastic. The paint schemes changed over time also. The grilles that we installed on the cars were three colors. Silver on most of the grille, charcoal on the squares, and black in the recess areas.
I believe the original grilles were a gray/bone color plastic (pictured below). Then NOS was the silver plastic and last was the black plastic, painted silver. .
Yep, the egg crate portion looks like its just painted silver like the OP's. Although Shawn's silver grill looks "too nice" for a grill that was sitting in a box for 30 years. Not even a rub mark on the edges. Was it possibly repainted?
Some of the very early NOS pieces were exactly like what was installed on the cars (Gray Plastic). However the last batches of the NOS pieces were produced in Black Plastic and came with the extra gusset at the top center. The top edge of the black ones are also not beveled like the originals. If someone takes a pic of the top center of an original you will see what I mean. All this is basically immaterial as we don't care about any of that regarding judging, and accept both varieties. There are a few that care about original original original, but not many. I mean do people worry about original tires. There are only 2 cars I know of that have 5 original sneakers, so where do you draw the line? Duane
Both my car and Brads White Car have 5 original sneakers. The point is where do you stop with all this, because there is a visual difference between the original and repro G60-15 tires, just like there is with the grills. Has anyone taken a pic of the top middle of an original grill to see the differences? Duane
Unless your going to keep your GS a static display piece, you have to make some concessions to drivability. Original shocks might be nice to look at, but honestly, can most people really tell the difference between original Pliacells and modern gas charged shocks painted gray? Same for the Polyglas tires. I want to drive my car, not roll it out onto a grass field. I see that with the Mustang Club "thoroughbred" class. Ive seen Boss 429's pushed out of trailers on the show field because they don't dare start the engines up and ruin a $5k NOS exhaust system or burn the paint on the engine. I know some people get off on that but its no fun for me.
