what part is this?

what is prat 4? i know part 3 is the shifter bushings that i saw when i took apart my shifter when i installed my ss

so part 3 is the shifter bushings shown in this pic

but does anyone have a pic of what part 4 is?

In my Acura catalog at home it calls it a Thrust washer B.

i knwo what its called but it doesnt help… cuz part 3 is thurst washer A… i just wanna see a pic of part 4 so i know whether i need a new one of that when i get new shifter bushings

I don’t have a picture, but its a flat white plastic or nylon washer…I would replace it.
