Inliners International Forums General Discussion Engines 1955 261 from 6400 Dump Truck,,YELLOW

Hello all, I just brought home a 1955 261 from a 6400 dump truck..engine needs to be completely gone through but I have looked for the yellow paint from Filling Station, Truck Shop and many forums...no luck. I know it has been asked here before but figured I would ask again.

Does anyone know the color code for the 261 between 1955-1957 that Chevy had painted Yellow? I would really like to go back with the original factory color. Thank you for any help.
