'68 Sunfire Yellow paint code please

Hey guys, I tried to search but found nothing. I want to get a couple rattle cans of sunfire yellow made up at the local paint shop and I want to have as much information as I can to give to them to make sure I get the right color. So if anyone know's the paint numbers for 1968 sunfire yellow I'd appreciate it. Thanks!

Y2 is the code in 69 for sunfire yellow.
it is also used in Gm cars as mayfair yellow.

1968 Plymouth "sunfire yellow" paint code is "S"
1969's "Y2" & 1970's "DY2" is the same color!!

GM's color code "40" used on various cars '65,'67-'69:
Pontiac "mayfair maize" / Chevrolet "butternut yellow" & "crocus" / Oldsmobile "saffron" / Cadillac "colonial yellow" / Buick "cameo cream" & "bamboo"
.... is a similar shade of yellow. However, it does not have the same formula!!

I was pretty sure the formula was the same?
Oh well, my friends GTO is now a Mopar color.

With all the changes in the paint "industry" , 40+ years ago they were different .... today they may be the same?
