Av-8b ???
That Harrier link has some remarkable stuff;
Leading photo is of a two-seat AV-8A Spanish Matador !
Two GAU-12 cannon ?
Wing area is different for US & UK aircraft, as the latter have LERX of various sizes.
The GR5 had the dual mode laser / tv ARBS tracker from new, the main addition with the GR7 was FLIR, some display updates & digital moving map.
GR9 to carry Amraam ?!
