Art....nice description of where to hook up, however, I was able to locate the front "J" hook holes in the frame but still confused about the rear. I have the same type of rectangular holes near the end of the frame in the rear which makes them unusable as they are too far back. The cross member which is forward of the spare tire has 2 round holes about 2 inches in diameter that would accomodate a standard type hook easily, but I can't seem to locate the 2 sets of rectangular holes mentioned in your post. Can you enlighten me??? Thanks Chris
