I believe that the tie rod having an integral tie rod end on one side, or having two separate tie rod ends is not a year to year thing. If I remember correctly when I got new tie rod ends for my 1988 V10 Suburban, they needed to know the gear ratio. Above the split got one design, below the split got the other design.
That being said. You already have a badly bent OEM one, I have seen lots of them bent as well. Just buy the ORD heavy duty setup. The parts need replaced, just do it once.
