Body & frame:Dont know where to look

ok, so after the most recent hurricane came through, a bunch of branches fell on my beloved truck, now it has enough dents a minor scrapes that i don't really care about any new ones, but the dome light cover for the bed light, (not the cab light) has been broken off, i have tried all the major auto parts stores like rock auto, auto-zone etc. i would like to find a replacement asap because i don't want the headache of dealing with the electrical system problems that are soon to come with the exposed electrics. does anyone know where i can find a replacement part. i talked to my dad who bought it new and it is the original cover that came on the truck. Thank you for any advice/help
