I am still working on my Abrams M1A2, and I have just finished scratch building some infrared IFF panels- the square louvre type panels on the turret. Can anyone tell me how they are attatched? I could just glue them on, but I am trying for realism and therefore wondering if they are bolted on, or held with straps. Also, the Dragon kit that I am using does not have the rear towhook included in the kit! It appears that they neglected to make this part, as the rear panel of the kit does have the protusion for the towhook, but the hook itself is not included. Any advice on how to make this part?
