Does anyone know why or when the change was actually made. I can't find any information on this and all I have been able to do is look at cars on ebay. Then interesting thing is that when I look a 85 300sd's some have the 84 set up, the thing that really has me confused is I found a 1985 300sd that was made in 10/84 and it has the different style air cleaner that is closer to the passenger side fender. Then I found one that made in 3/85 and it has the 84 300sd set up. If anyone could please explain the difference and with set up is better please let me know. I also notice that the cars that do have the different set up, the turbo looks like it sits higher that on most of the 84 models.
