Race payouts have to do with what contingency logos the drivers car is carrying. If you dont know, the contingency logos are the ones in front of the car number under where the rear view mirror would be. These are the logos of various in race sponsors, for example back then you had True Value Hard Charger award but if your car didn't carry a True Value sticker, you didn't get paid for it. Heres an example, back in the early 90s when Rusty first started driving the #2 Miller Genuine Draft car for Roger Penske, his car barely had any contingency logos on it because that's how Miller Brewing wanted it. Because of that, whenever Rusty won a race, 2nd and sometimes even third got more than he did. Made sense to me, you wanna be paid, you gotta represent. Jr's car must be missing some important contingency decals because his primary sponsor either didn't want that because of the paint scheme layout, or they have some kind of other conflict. Doesn't matter, Jr's making enough cash outside the car to more than cover whatever lost on track.
