rodtek , go to www.newstalgiawheel.com/wheel_visualizer.asp . On left side of page , click on wheel visualizer , then select vehicle ( 60-66 Chevy truck ) at top of next page and wheel type at bottom of page . The visualizer allows to see not only what each wheel would look like on your truck , but also allows you to " lower or raise " the truck . Maybe this visual aid will help you decide how much you want to lower your truck for the look you're after ?
