Honestly . . . I have no idea. I would assume it is aftermarket but dont know what or where. It does have those corners though. I bought the truck a few years back and the gent I bought it from had done a "redneck restoration" on it and it was pretty rough. It seems that If I didnt replace or rebuild it when I went through it (total frame off) it has broken or malfunctioned in the 1500 miles I have on it so far.
Blah, blah, blah, blah . . . and I really mean that.
