Black Stealth Running Boards- Parts??

I’ve identified these boards as “Stealth” running boards, looks like they are an OEM option. They have no manufacturer markings anywhere on them.
I busted one of the end caps on a stump, and I can’t find how to get a replacement cap.
Any ideas?

 

Usually dealer accessories are sold as a set and one cannot buy a individual part but must buy a new set. You might get lucky if there is a used truck with the running boards sales may be willing to sell you that piece not horrible likely but may be worth asking, it would helpsl if you ask the dealer who you bought the truck from. You may also be able to find individual parts on Ebay but they may be a knockoff and not look right. Or you could offer to buy that part off someone here with the same running boards.

 

Update: for anyone else who runs into this:
Sparks Toyota in South Carolina found the parts for me. The part number is 00016-34083-03 and it’s $40 for all 4 end caps! Maybe this will help someone in a future search.

 

I have these installed as well. Good to know!

 

Well goddamn, good job.

 

Is there a better part number? The one listed goes to the tundra full set. I scored a free set but need an end cap as well.
