No place to secure topper on my bed?!!

Hello beautiful community,
My 07 Tacoma has no place to secure my topper I tried using clamps and there’s no place to use them it’s just stupid plastic. No where whatever so ever .
this topper came off from Ford Ranger .

 

More info needed. Second hand topper? I'll send pics of my clamps tomorrow. They fit in the adjustable tie down slide rail, and would probably work with most toppers.

 

Obviously , as I cannot afford one made for tacoma

 

LIke the previous person noted, the clamps for Tacomas use the rails on each side. One part goes in the rails, and the other part is drilled through the topper. At least that is how my Leer was installed when I had it. There are a few different options but most will involve the rails and either a top-down clamp or through the topper in each of the 4 corners.
