Third week of November 1969. The carburetor is not the original carburetor for the car, it is however, close enough for me to date correct, and code correct. The carburetor came off of a 1970 Chevelle with a 350 and 4 speed. The carburetor on the car when I bought it was Rochester Quadra jet from a 1969 truck, I still have it. I try not to be too fussy about that stuff I simply got lucky when I found the carburetor.
