Rochester 2 bbl date code info?

[TOG1937]

Anyone able to de-code this date code?
Carb number appears to be correct for this YC code '66 290HP Cat.
Thank you!

Sorry it's a Later carb.... 67+ all side stamped ( it's an early 67 carb ...day 29 of 1967)

Earlier would have carb id stamped brass tag attached to a screw on top...


60 and 62 ( last numbers found close to your #s ) are for 67 326 and 67 400
