You've probably seen this version from the Argentine Air Force website?

'Tres M-5 Dagger, indicativo "Oro", armados con dos bombas retardadas por paracaídas. Tripulación: Capitán Raúl Díaz (C-419), Mayor Luis Puga (C-410) y Teniente Carlos Castillo (C-430). Despegaron de San Julián a las 10:24 hs.'

I can't imagine them mixing up the pilots and airframes. I was always under the impression that it was Dagger serial C-410. The above info would make it C-430.
I was in the Falklands during 1998 when the nose section of an IAI Dagger was found. It was found if I remember correctly near First Mount, Elephant Bay. The wreckage was discovered by chance by a hotelier who was out walking in the hills. It appeared to be the nose section as the remains of Lt. Carlos Castillo were found. I have no idea if the wreckage was left intact or removed. Possibly the Falkland Islands Museum might be able to assist?
Quoting from the 1986 "Falklands: The Air War":
"Both of Auld's Daggers fell into the sea north of Pebble Island, while
Smith's impacted on the western edge of Elephant Bay on the slopes of
First Mount. . . Castillo therefore appears to have been the been the
pilot killed in the First Mount wreck."
And in the individual a/c histories:
"C-410 . . . Brought down over Pebble Island . . . . Teniente Castillo
was killed in the explosion. The wreck site has not been positively
identified but may be that found in the First Mount area (UD 170160)."
I remember reading in the RAF News an article on the funeral service of Lt. Castillo. An article appeared in a UK aviation magazine which, if I remember correctly, had details of the 'kill' markings found on the nose section from when it was last in Israeli service and an Israeli call sign plate found in the
cockpit from when the aircraft was an IAI Nesher.
I no longer have the magazine, but the call-sign plate could assist the match up between the Nesher serial and subsequent Dagger serial?
I think that the aviation magazine was Aviation News/Air Pictorial?
