In 1977 the tie rod went from being on top and going down (nut faces down) to being on the bottom and coming up (nut faces up). This knuckle is for the style where the tie rod is on the bottom coming up. It will fit all these years but you may have to change your tie rod.
The picture in this listing is representative of all I have available. All are comparable in condition.
