yeah, a number of things don't 'look original', but if it's not rodded, it's original
it looks like a cared for truck of factory configuration, which means if the engine isn't trashed and there's not a couple gallons of bondo under that purdy blue you did fine! seems like decent paint, and it does look like you'll be able to just get in and drive
enjoy the ride, and keep us informed - you'll find lotsa help here to sort out any problems
