It will work either way though it does matter If my memory is not wrong.
For when doing an alignment and you are adjusting toe when you need to bring both wheels in you should be moving both adjustment turns in the same direction. If moving the LF wheel in by moving the wrench to the front of the auto moving the RF wheel should have you move the wrench forward as well.
Though my disclaimer is it has been a long time since I did an alignment and never on a 1952 or 1954 Chevrolet truck.
I agree with Denny regarding orientation.
Regarding the adjustment:
If you are adjusting toe-in, you simply loosen the nuts on both tie rod ends and put a monkey wrench on the middle of the tie-rod and rotate the tie-rod.
1947-55 (and other years) toe-in adjustment You are then either moving both sides inwards at the same time or both sides outwards at the same time (for either more toe-in or for more toe-out).
(Maybe I am mis-reading this thread - sorry.)
