The radio hood ground clip number 346160 and the screw that attaches it is 9431798 per my 1974 Camaro Assembly Manual.
Interesting. Mine's a non-HEI car and it doesn't have that gizmo. But there's a small hole in the cowl in the right area for it. My car is built April 15, 1974 and I believe it's around the end of the points cars so that may explain that small hole. Does zfool's car have one? I know his is a very late '74.
We’re close, I’m third week of April, have HEIInteresting. Mine's a non-HEI car and it doesn't have that gizmo. But there's a small hole in the cowl in the right area for it.

How cool. my last VIN digits are 189769. I was able to get the exact production date due to my Canadian vintage GM documents. So the changeover to HEI must be just days after April 15/74.We’re close, I’m third week of April, have HEI
Do you know if all the 74 Z28 valve cover bolts were like this recessed head with letters or just the HEI motors with the 8 mm wire brackets. . Mine has them too , I thought them a bit unique as compared to other SBC I had from the same period .![]()
is it possible to make them in the grey color like the factory ones? I suppose some SEM paint would work.

My car is also a 2B. I have points dist, NO HEI air cleaner dent, Muncie M20 transmission.I have two sets of the valve cover bolts and both sets have the "R" with the ridged heads like in your photo. One set came off a car with HEI where I got the HEI wire holders and the other from my car which was not HEI. Learning about the hood ground clip, which I don't have, is another way to help me confirm it was not originally HEI. Oddly, my air cleaner has the HEI dent and since I didn't have the correct points distributor, I went and found the correct HEI distributor just to make it pointless. My car is 02B, second week Feb.
My VIN is 159084 - out of curiosity, how close is it to yours?My car is also a 2B.
