It's important to note that there are two types of rear reflectors used on LWB and G-Series taillights. Euro taillights have no assembly for small running lights and the reflectors used for those have four legs and no notch on one side. The U.S. taillights have a large assembly for running lights and the reflectors used for those have no legs and a notch where they snap in the holder on the reflector assembly.
The new ones available only come with the four legs in no notch. They can be made to work in the U.S. taillights by snapping off the legs and super gluing them in place. However we do have original U.S. reflectors in excellent condition available without legs and with the notch.
