Has anyone seen the con vin stamped on 66 chevelles near the heater box or on the cowl as have been found on 67 chevelles built in Alanta?

not on my Framingham car and I looked hard for it when I thought 66s might have been stamped. I don't think that anymore.

Thanks Tom, I also don't think any of the 66's were stamped; but after seeing that the Atlanta 67's were stamped, thought I would start a thread on 66's to see what was generated.
