OEM Bed Rail System?

So I just picked up an 05 Tacoma the other day. It came with an Access Vanish Tonneau cover (which BTW is for sale), but the tonneau cover apparently required the rail system to be removed. Long story short, I want to put a camper shell on and it seems the only practical way to do this is by utilizing the rails.

The problem: I can't seem to find the rails listed as any sort of OEM part. I did a lot of searching and haven't found anything for sale. Do you guys know of a place where I can buy the rails? Or should I just see if I can't find a tacoma in a scrapyard and pull them off of it?

Thanks for the help!

 

Anyone know anything about this? Local salvage yards won't separate the rails from the whole bed. It's buy the entire bed of the truck, or nothing.

 

I tried getting a extra set from local dealer and Dallas Toyota. Both said they are not listed in the books or on the drawings. Looks like the scrap yard may be everyones only choice.

 

See if u can find a rear end wreck, with the bed wrecked, but the rails ok.
Have your local junkyard do a national search.
