Does anybody know why John Deere used so many different style side cover on the square fender series an what is the purpose of the solid verse vented or meshed? Which of these are more desirable for certain models?

I believe the ones that have the screen were  only used on the 1975/76 models. All other 200 series had the louvered covers. As far as I know the solid ones  are only used on the 300/400 series. Anyone can correct me if I am  wrong and I have been known to be wrong often, just ask my wife she will tell you.
