Solving The 4x4 Tie Rod Puzzle??

[72longbed]

This has probably been asked before but, here goes again. Who can get me the proper MOOG or TRW part numbers for the 1971 3/4 ton K20 front tie rod ends that attach to the long rod that connects both knuckles together? I have been trying with local parts stores, , and they don't seem to know their 'a$$ from a hole in the ground'. They keep giving the parts for a 2WD front end or the tie rod ends for the draglink. It's sad the lack of talent at most parts counters today.

My 3/4 ton Dana 44 has the tie rod ends that go into the knuckle from the top with the 'castle' nut on the bottom side.

I need you early 4x4 experts to come to the rescue please. Even the correct GM part numbers would be great so I can cross reference them to a MOOG or TRW.

Thanks,
