I know the feeling. LONGBOX55 told you right; '60 and '61's had quad lights as did '58 and 59's. '60's had twin-pods in the hood with the park lights centered in the pods. My first pickup was a '60 Chevy Fleetside, 6-cylinder. Wish I had some pictures to share with you but I didn't keep it long, maybe 6-months or less. Let my baby brother talk me into taking his '65 Fleetside, 283 O/D and giving the '60 in trade. Motorbooks, now MBI, put out a nice Chevy truck book in the Crestline but with slick pages and really good photos. Maybe someone close has a copy that they will let you look at.
