Dupli-Color Engine Enamel DE1618 Detroit Diesel Alpine Green

People have suggested these for yellow 261s:
12 oz. Farm Equipment John Deere Yellow Gloss Enamel Spray Paint
Daytona Yellow (from Cosmo)
"Edsel/Pacer" yellow (amtrakjoe)
VHT Yellow engine paint
Duplicolor Daytona Yellow engine paint
Rustoleum Daytona Yellow engine paint
Eastwood Yellow 650 degrees paint
The Duplicolor Detroit Diesel is a nice color for the 261, fairly close in correct color. Plastic kote alpine color is the closest to the correct color that I can tell but plastic kote is no longer available. The detroit diesel green is in my link in my signiture.
