US Navy OV-10A Bronco / Black Ponies VAL4

Going to get a 2 ICM OV-10A Broncos , one will be a dedicated build for the Navy Val 4 " Black Ponies " is there any difference in the onboard weapons stor between the Marine version and Navy version ?
Will need to get the decals for the Navy Bronco as well , what would be my best option for the decals ?

Shouldn’t be a difference between the ammo as I recall.

For decals there was a AOAdecals - 1/48 Decals
or Caracal decals.
