utility track in bed missing.

Ive seen some tw member tacoma pics and ive noticed that in the bed of the double cabs it has some kind of track towards the top bed rail. It kinda looks like you could tie down stuff using the tracks. Anyway, i think mine are missing or atleast they wont on their when i bought the truck. I was just wondering what they are and what its called. Has anyone ever had to order one? Ive got screw holes where it looks like it was their at one point but not no more.

 

The bed rails?
There should be 3 channels. One on each side of the bed & one in the front.
All the 2GEN models come with them & 4 bed cleats that snap into the channel.
It sounds like the previous owner took them out?
Usually just the cleats get taken.

 

I guess a toyota dealer could get these for me? Do you get alot of use out of them and are they worth getting? Anyone know price of these?

 

I think the adjustable bed cleats are useful. If you check the 2nd Gen Marketplace on here there are some members selling them.
