This set includes three (3) pieces that make up the belly strap found on late F-4E and all F-4G Phantoms. Designed to be used on the Revell kits, it may work on the Tamiya kit as well. 

The strap was also found on the F-4S and the F-4J's operated by the UK. 

Parts come as shown and can be removed using sprue cutters or a sharp X-Acto type blade. Light sanding may be needed to remove any remnants of the support nibs along the edge.  Use Super Glue (CA) to attach to kit.
