There might be a chance for me to pick up a '93 E400 cheap at an auction. I currently have a 87' 300TD. I have already planned to swap the corner and tail lights. Also the, temp display and instrument cluster (I plan to convert the economy vacuum gauge to a boost gauge). I have determined the brake setup on the E400 will be a nice swap to the 300TD as described on this site -

Any other suggestions? Sway bars and such?
