AHC: Brazil in Falklands War

I need some ideas for a timeline I'm thinking of writing. Your challenge, if you wish, is, with a POD no later than 1965, to have the nation of Brazil jump into the Falklands conflict.

Given the traditional rivalry between Argentina and Brazil (as noted by several), I'd think if Brazil DID jump in, it would be on the British side.

Yet Brazil did provide some assistance to the Argentinians during the Falklands War - maritime surveillance aircraft were lent to Argentina during the War, flying Argentinian colours; also, some MB-326 aircraft were ceded to the Argentinians, but I don't remember whether that was during of after the war.
