C2 Chalk Mark

[frank clark]

I am posting a photo of the center clamp plate on the rear spring of my 66 coupe. Is this a possible factory mark, or was it drawn by Bubba's kid when While he was installing the 15x12 keystone mags?
Thanks,

Is that center bolt bolted all the way through with a washer on the underside?

Wayne,
I took this picture about three weeks ago. I looked at this picture and some others I took. I have not removed the spring from the car. From what I remember, the bolt is bolted through the spring. I cannot see the head in other pictures I have. I believe the nut is tightened against the spring without a washer. Do you see a problem?
Thanks
Frank

My guess would be its an inspection mark. The inspectors on the assembly line often mark items on the cars as they go by as a verification that the part is in place. It was quite common in the assembly plant I worked in a few years ago.

Re: C2 Chalk Mark

I have the same mark on my original 66BBCoupe. Since I have all original inspection marks and hash marks, in evidence, I assume this to be inspection mark.
