Threaded holes on bed rail under rear window

For the 2017 tacoma there are 2 Threaded holes on the bed rail beneath the rear window. Anyone know what these holes are for? I'd like to use them to mount a bike rack to since I do not have a front rail system. What you the size be?

 

Those holes are for the OEM tonneau cover. There's a small bracket that goes there if you have the OEM cover.

Also myself and many folks have added the 2nd gen front rail with no issues. I suggest you do that. The bolts are already there, just buy the rail ~ 50 bucks.

 

Ok great thanks. Any suggestions on where to buy the front rail?

 

Try your local dealer. Price was as good as I could get it shipped to me for from somewhere else.

$56 PT278-35100-BH Truck Bed Header Rail

PT278-35100-BH

It was something like $34 or so.

Doesn't come with the plastic end caps; I've not missed them but will probably pick some up one day.

 

Ok thanks for the help

 

Anyone happen to know if you can replace this bar and hoe much it is? I drilled holes into it for my softtopper snaps and looks fine. Just curious if I were ever to get rid of the softopper and not want the snaps / holes anymore.

 

If I understand it correctly, it looks like it might be $309 - if you wanted to get it, I'd probably wait until the dealer has a parts discount.

I mounted a bracket there. I think they are 8s.

 

Here’s a pic of one of the snap screws installed in the metal bar I’m talking about. At this point I’m not interested in replacing it, but was just curious if I switch things up in the future.
