You will need the 
MESH_ju-beos_slimtop050802.package mesh for these to show up in your game. 
Here are 8 rolled-up sleeve tops for Marvine's slimmer bodybuilder. 
They are organised into 2 sets with 4 tops in each set. 
Set 1.
 
 Set 2.
 
  Credit goes to Marvine and Beosboxboy for the mesh and muscle shadowing and wirelessguy for the textures/alphas.
