9-11 cars that had only small changes like the Hendrick cars
Henricks's cars had more than 'small' changes to be honest. Flags on the hood, I Love NY decals (however the #24 didn't have those), and 'GOD BLESS AMERICA' on the trunk.
If any cars had 'small changes', I would be looking @ the Petty cars. The #45 as far as I can tell, only had a small USA flag below the B-Pillar. #43 the same, but a flag on the hood too. As for the #44, they had the B-Pillar USA flag too, but had a bigger 'forever in our hearts' decal in front of the rear wheels that the other 2 Petty cars didn't have. None of them had the 'I Love NY' decals as far as I can tell, since the cars only added them on race day.
