Help me ID my tonneau cover rails.

Hey TW,
First real thread I'm starting so please let me know if I violated any forum rules/etiquette.
I recently picked up this 07 Tacoma, it's a 4x4 v6 access cab, and with it came some sort of tonneau cover mounting rails. My previous vehicle, a 96 T100, had a soft cover that flipped up in three sections and attached to the bed via spring loaded hooks in the four inside corners of the bed. I really liked that cover due to the ease of removal.
The new truck has rails on the top perimeter of the bed. Look at the attached pictures. I don't have the actual cover, nor do I see any information on the rails.
I'm looking for any information on the rails, if a cover is inexpensive I may just buy the cover to match the rails. However I would prefer to switch to the other style cover. If anyone is in need of the rails I would be willing to part with them for a very reasonable price so I can put the money towards a new cover.
Thanks for looking, Teddy

 

Looks like it's from an entry level cloth tonneau. I had one like this on my previous truck, and the tonneau has these circular plastic clips along the edges that snap into the rails.

Yours.. looks incomplete? You should have a piece on the back. I don't think the rails are worth anything if you don't have the actual cover.

 

Thanks for the reply, off they go.
