As Poncho says the hood emblem looks like a V8 emblem although the pics are not that clear. If a factory V8 the first digit of your VIN will be a V. Try the VIN decoder here
http://www.americanclassic.com/ the button on the left. It will tell you whether it was factory V8, series truck, the year, assembly plant and your truck production number (starts with 100,001 for first truck at that plant for the YOM.) Let us know what you have. Don't believe most of these older trucks had a trim plate per se. My 59 has another plate just below the VIN tag which is larger and blue which has the paint code stamped on it. I'm computer challenged or I would post a pic here for you. Email me if you need a pic emailed.
