I just did my 300E and my wifes 300D, and it is not easy. I had the car up on ramps, make sure you put something behind the rear wheels so it doesent roll. You can get the one under the gear shift from there. The one closer to the tranny I had to put the car in drive to get to the bushing, still tight. I put the new bushing in the microwave just enough until it is soft and then put it on the car, the one by the tranny took me a few tries. Just take your time, make sure you put something behind your rear wheels, I also used a screwdriver to help get the bushing in.
