Tie rod Difference???

So long as you are buying Moog you're good to go. And there are better sleeves available, from a Diplomat or 5th Avenue. They are bigger in the middle and narrower at the ends where they are threaded for the tie rods. The thicker sleeves deflect less while cornering. I think the 73 style tie rods should work fine. I do not believe they changed the taper where they connect either to the drag link or the lower ball joint from 68 to like 73 or so.
