it was a deflecta shield box from autoanything.com. not sure they have them on there anymore. prolly better off to get a chrome one from lowe's the same style for cheap, then paint/PC/line it
The box looks really close on not fitting all the way, have you had any problems with it sliding or comming off?
@prerunner366 it was attached well and never moved. after i got a shell, i cut the thin "wings" off and essentially converted it into a chest style.
