Hy sky nighthawk, sorry I missed your post from a couple of days ago, so far all I can find are crosses to the standard duty tie rod ends.
GM p/n 609747 is the left one = Napa p/n NCP2692019 $59.95
GM p/n 609748 is the right one = Napa p/n NCP2692020 $59.95
Gm p/n for the heavy duty left one is 2275620, no cross at Napa
GM p/n for the heavy duty right one is 2275619, no cross at Napa
I'll do some more looking for the Heavy duty ones, you could check Ebay, hope that helps.
I found Ebay listings for one each of the heavy duty tie rods, here is the link (I hope it works)You can actually search for it by part number, and it will come up with the tie rod ends!
