Default Holley Carb Help ?

I have picked up a holley for my 67 that I am afraid is an over the counter replacement. I think I have the date digits backwards..
The part # is 3906631-DA
the other List 3810
date 2926

Is this a , made in 66 unit or a made in 72 unit ??
Thanks

That's a later Service replacement, made on the 292nd day of 1976 (or 86). Holley changed their date code format after 1972 from 3 digits to 4.
