OEM Tonneau Cover

Hi everybody, just put the Tacoma Tonneau cover on today all good expect 2 extra rubber bumpers or stoppers were included with the hardware not sure where or what they’re for? Any insights ?

 

My lovely other half figured it out. These must go on at the cab end of the bed at each corner or your cover will leak. If you’re putting a new cover on make sure these puppies are there..

 

What he said, tho I've no idea how they fit. Bought mine used off a friend. My rubber pieces sat in cup holder till I removed the tonneau yesterday to put on my new bed rack. Lol

 

I’ll post a pic tomorrow I just shoved them in by hand so didn’t have to take anything apart to get them in.

 

They fill the gap between the header rail and bed rail covers.

 

Windy and rainy yesterday and today had water coming in from more than one spot you can see daylight from inside top left and right corners maybe OEM cover nah tha best??
