       8 . A cargo shift stop assembly according to  claim 7  wherein said spring is mounted on top of one of the cross members in siad flatbed or dry van trailer.  
   
   
       9 . A cargo shift stop assembly according to  claim 8  wherein at least one key slot is provided in said collar.  
   
   
       10 . A cargo shift stop assembly according to  claim 9  wherein a pair of key slots are provided in said collar for a pair of cooperating keys.  
   
   
       11 . A cargo shift stop assembly according to  claim 1  wherein a tapered bottom is provided in said plunger.  
   
   
       12 . A cargo shift stop assembly according to  claim 11  wherein said tapered bottom in operation stops said plunger at a pre-determined height.  
   
   
       13 . A cargo shift stop assembly comprising: 
 a plurality of cargo shift stops mounted in a strip of solid material adapted to be recessed into a preexisting floor.    
   
   
       14 . A cargo shift stop assembly according to  claim 11  wherein said strip is made of a material selected from steel, aliminum alloy, and composite material and combinations thereof.  
   
   
       15 . A cargo shift stop assembly according to  claim 14  wherein said strips are mounted in a transportation vehicle.  
   
   
       16 . A cargo shift stop assembly according to  claim 15  wherein said strips are mounted continuous from the front to the rear,  
   
   
       17 . A cargo shift stop assembly according to  claim 15  wherein said strips are mounted continuous longitudinally from the front to the rear,  
   
   
       18 . A cargo shift stop assembly according to  claim 15  wherein said strips are mounted continuous transversely from the front to the rear. 
 typical dry van trailer, or other floor, the floorboards are continuous from the front to the rear, or are longitudinal from the front to the rear.    
   
   
       19 . A cargo shift stop assembly according to  claim 15  wherein said strips are laid side by side next to each over cross-members of the floor.  
   
   
       20 . A cargo shift stop assembly according to  claim 15  wherein said strips are laid in a way engineered for that particular trailer or flooring platform.
