4 spd. pops out of gear.

Thanks Jeff would you be able to tell me the proper #/letter of 1st and 2nd shifter tabs?
I`m not sure they`re correct.

All numbers/letters face out so you can read them, 1-2 should be LOW or L, 3-4 should be DIR or D, reverse should be REV or R. All point up on a regular 4 speed and only 3-4 points down on an O/D.
