You can use a 1/4" bolt, there's a hole that goes through the shifter mechanism, to align the levers. Make sure that at the trans side cover, the arms are in the slots, there are pictures back in the threads , make sure that everything is in it's proper place..
Let's see if my pictures load.
When I installed it all back in, I did use a bolt to align the shifter...maybe I did something wrong or perhaps my shifter is bad? I will climb back under and re check to see if i can still get a bolt in there...
