I think I messed up...somehow. I've been restoring my truck, and when I got the truck, it had no seat brackets on the bottom of it. That's fine, so I ordered some from somebody. Now when I go to put them up to the seat, I have no idea how these are supposed to mount up. Nothing lines up. Its a bench from an 81. The brackets, I don't know what year. I feel like I'm missing something on the bottom?
