Note that of the various tail light lenses shown, the above 'Gr-4-type' will NOT work in std buckets because the reflective dividers inside are specific to the kind of lens used. For these, you need the whole assembly. Hall Pantera used to sell a 'conversion' kit so GR-4 lenses would work in std buckets. Haven't seen one in a decade. Also, all the tail lights are left and right handed so you can't take two left side units and bolt them on properly. Sorry, bargain hunters.
