I am about to replace all the steering tie rod ends. The parts store got a bunch of wrong parts for me and then got the right ones but in this process all the ends got mixed up

I have 2 inner and 2 outer. I know the inner are the long ones and small are outer but what threads go where?

ie. left hand threads go where?

wouldn't it make sense to cast these parts with the placement? Like a big R or L. jeez

'Tis a right of passage, my son ...
