I added the values from the fbx file to these arrays.

Code:
verts : array [0..11] of GLfloat = (
   -2.5,-2.5,2.5, -2.5,2.5,2.5,  2.5,-2.5,2.5,  -2.5,-2.5,-1.69999992847443
   );

   texCoord : array [0..11] of GLfloat = (

       0.00744416890665889,0.915632724761963,  
       0.00744416890665889,0.468982636928558,  
       0.454094290733337,0.468982636928558,    

       0.355433821678162,0.454094290733337,    
       0.838598906993866,0.00744416890665889,  
       0.355433821678162,0.00744416890665889   

  );
  v_index : array [0..5] of GLInt = (1,0,2,3,2,0);
