Exactly (except for the chicken lights).
Any truck modeler would know that.
Thanks for your first impression review of the kit.
As for the glad hands. There are after market gland hands, scale hinges of many types as well has other after market items. Stripping the chrome is something that should be done on every model kit. The factory plating is always too thick and not very realistic. Stripping the chrome always exposes more of the molded detail. Alclad, for example has many shades of metal to accurately reproduce many materials.
