'15 Limited Crew Max - Side Step Pads

I need help from the forum members in trying to identify my side step rails. This is a 2015 Toyota Tundra Limited and purchased Used by me back in 2017.

Well on the driver side of the truck the step pad has come loose. There's about 8 rubber/plastic inserts that have broken off the pads themselves and currently only being held by one.

The pads are not rubber and made of plastic. I've searched the inter-webs with no luck. I'm also unable to find a part number marked any where on these rails! Very Frustrating.

See pictures attached and see if you are able to give some me a clue.

 

Watch Craigslist or FB marketplace for a set of tubes. Many install sliders and sell the tubes for about $100.

 

Another option may very well be some marine epoxy.

 

I like the marine epoxy idea, that'll get me by for a bit while I search for replacements! Thanks for the input!!
