Anyone have any ideas for attaching a tow bar to a 4 door? I have removed the stock bumper and fabricated a 12-pack (becuase that is how many it took) tube bumper. There just seems to be no place to mount the tow bar and the bumper is attached with the 4 stock fastener locations. I just don't feel comfortable attaching it to a home made bumper. Any help or pics would be great! Thanks!
