I asked that Mark guy whose dad used to work for the Datsun dealers in Phx about the Datsun emblem story during one of my visits to his place, and he said he thought there was a dealer over in west Phx that would swap them out before they put the Patrol on the lot.
However, since this Patrol was also once owned by one of Phx's most devout Datsun-Dorks, The Ebay emblem swap-out possibility is an equally likely possibility (and, it's a term of endearment, people, please don't get offended... I used to classify myself as a Corvette-Kook

)
Kris- Mark's dad may have also been the one that fitted the FJ40 rear axle under your Patrol - he said his Dad did at least 10 of those conversions across the southwest during the 80's and 90's, and he still has a Patrol-modified Toyota axle sitting on his property (unless he has sold it since my last visit)
