I need the left side, and can I reused blindspot monitor, and all other parts ? I just broke the lens I need to get it replaced, So do I need to buy the complete light assembly , or can I just get a lens ?

Hi, in general, for tail light lens assemblies, the glass or plastic lens is not available separately, as the part is bonded in place by the factory. While we list the complete tail light assembly on our site (see link below), unfortunately, the part is not available as an OE part at present. We apologize for the inconvenience. https://www.carid.com/2020-ford-f-250-oem-lighting/ford-oe-rear-lamps-tail-lamps-2460534670.html
