1968 Tail lights
Are the 68 tail lights lens the same diameter as the 1974 lens ? I was thinking I might replace the bubble lens I now have with the 68 lens if they are the same size. Can anyone help ?

The 74 lamps are about 5 1/8" in diameter, while the 68-73 lenses are 4 7/8" diameter. Being slightly smaller, the lens should fit ion the bumper, but the 68 lenses are hooded. From about 2 to 10 o'clock, the outer edge of lens is flush, but from about 10 o'clock to 2 o'clock, the top of the lens has about a 1" wider "hood" on it. This hood would likely stick out of the top of the hole in your bumper.
The 74 lamps were a one year only design, made up of a lamp housing and lens, bonded together as a one piece assembly. 68-73's and 75-79's used a two piece tail lamp, with a separate housing and lens, held together by screws. The aftermarket bubble lenses are made in two pieces, like the 68-73 and 75-79 tail lamps. Unfortunately, you can't use 75-79 lenses, because they mount with 2 screws, while the 68-73 lenses, and the bubble lenses, use 3 screws.
