I am in need of atleast one front turn signal lens for my 74 wagon. The drivers side one is broken to where the light socket wont twist into it anymore. This makes the bulb and socket fall out to where you cant see the light anymore. They look exactly like the 71-73 lenses so I was wondering if the 71-73 lenses were interchangable with the 74-75 lenses and grilles? Also will a 71-73 grill work in my 74?? I need one of those too...
