7 tooth retainer clip

[izze]

I have a lot of slop in my steering. And I just came across a new steering wheel. So I am currently taking apart my 7 tooth box to make sure everything is as good as I can possibly make it, before I swap out my steering wheel.

My question is in regards to the worm gear retainer clip. I was able to easily remove the clip in two separate pieces. And I am unable to locate the replacement part number for this clip. Or any images of what it should look like.

The gear is still on the shaft. It has about 1/8" to 1/4" of movement along the shaft. But does not slide off the shaft. I have not tried to forcefully remove it. And I do not think I need to replace it. (yet)

I have found a lot of odd part substitutions when addressing other issues on my vehicle. And I wonder if this is another one. Can anyone tell me if this is the correct retainer clip? Or where I could locate a replacement part if it is not? Also, is the 1/4" of movement something I should be addressing?

Thanks!
