Rear drum brake help

I'm working on replacing my drum shoes and cylinders on my 03 tacoma prerunner. I have the auto adjusting wheel but not the piece that interacts with it. I bought the truck used with unknown history of maintenance and care (I know I just really wanted a tacoma) anyways is that something I need in order for it to work correctly. Also I have a different attachment than any videos I've watched so it's really throwing me off I'll post pics shortly but help is very much appreciated

 

Didnt feel like putting the spring back in yet but this is the side without the adjuster

 

This is all I have on the side with the auto adjuster

 

And I don't have the adjuster attached in the photos, but I do have it just not the plate its that's supposed to interact with it
