I think Brundle at Detroit was the only Tyrrell ever actually disqualified in 1984*. That's why I said "read the fine print". The FIA wanted to come down hard on Tyrrell, but realized that wasn't going to be easy, legally. Every entry blank in the world carries the rule that after a short time window for protests, race results become official, and thus final - it's a pure necessity for promoters to be able to pay out the purse; they are never going to get back money they have already paid out, thus they need the disclaimer by the recipient that the results are accepted as final. But, the FIA is not in the business of promoting races, that's the duty of the national clubs, who are all members of the FIA, of course (and most of them, by the way, hired a certain Mr. B. C. Ecclestone to do business for them). Conceivably, the FIA could have ordered the national clubs to disqualify the Tyrrells, but I don't think they had the formal power to do so, and anyway, every national club would then have been liable to legal action by Tyrrell, if they so desired, and it doesn't take a legal eagle to work out that Tyrrell would very probably have won every case handily. With Tyrrell conceivably seeking court action in six or seven countries at once, and likely to succeed at that, it would have been a mighty mess, and the likely outcome nothing short of a catastrophe for the FIA!
But, the FIA sanctioned the World Championships, and since the Concorde Agreement in 1981, every team had to formally enter the World Championship competition through the FIA. What they did, then, was to "exclude (the Tyrrell team) from the FIA World Championship", and "as a result its entry is cancelled", that's the aforementioned fine print. With that, Tyrrell's results so far in 1984 were simply ignored within the FIA documentation of the World Championship, and regarded to be "outside of competition" for the same. That was within their powers, they simply struck them from their own records. Of course, all the statistical mumbo jumbo sites can't tell the difference, they have a hard time accepting that there was Formula One without a World Championship, and a World Championship without Formula One. And even if you're going to provide me with a link to an official FIA source showing that Arnoux was third, that doesn't make it any less wrong because the FIA wouldn't be the first organisation to rewrite history in their favour. No doubt, they'll give a damn about what pesky historians write, and it's their right to do so, but the fact remains that Tyrrell #4 (driver Stefan Bellof) was never disqualified from the results of the 1984 Monaco Grand Prix.
* It was the only time all year that results were declared provisional pending a protest or the outcome of post-race scrutineering, in this case the latter because the SCCA sought evidence from further analyses of their findings. This then triggered the FIA Executive Committee fine, in the light of which it seems unnecessary to actually disqualify Brundle from the Detroit race - however, the SCCA may have independently done so, and probably did.
