Offset upper control arm shaft

[68-97stepper]

Im going to revive this thread by asking for help.
IM looking for the offset shafts for the upper A arms on a 72 c10.

I have called, texted several suppliers who advertise the offset shafts----but when you read the description of what it fits the description doesnt include a C10 (only full size cars) and when you ask---"-Does this fit a c10 pickup" its like you ask about the theory of relativity----no one has a clue.
I know moog used to make an offset shaft but havent been able to nail that part number down either.

Im hoping someone can tell me (so I can tell the parts supplier) what the part number is.

thanks if you can help.
