Need Outer tie rods 72 4x4 front end

[rics34]

I put a 72 front end under my 76 blazer since that one had pass. hub blow to pieces from previous owners lack of care and being lower then a ford owner. I found a 72 front end and bought it, another mess due to it had bad ball joints and the axle bearings being shot. After putting that in and then having to rebuild it due to others not letting me do it right like I wanted.
Anyway I order them from autozone and got one right and the other box was right with wrong part in it. Autozone has quit carrying them now. Any clues where to get them from?? And will my 76 work in place of it?
