quick question on transfer case skid plate install

I have a 4 cylinder and I bought skid plates from RCI.
There was a small "skid plate" bolted to the bottom of the transfer case already. The instructions make no mention of this. I removed it before installing the RCI stuff. Is this part on all trucks or just the 4cyl?

If your new one fits, leave it. Like this...

 

I've never seen that on my 4.0
Keep it if you can

 

That is a vibration dampener weight. My 2014 4-cyl 4x4 Tacoma doesn't have it and I bought it brand new. It does have the little black painted steel skid plate.

 

I was talking about the little plate. I guess I’ll clean it up, paint it and reinstall it.
