Just took some measurements from my 87. They very about 1/8 inch from one side to the other though. On the drivers side, I get 1-7/8" from the gas door flap to the top of the E. That's also about 2-3/8" from the O to a vertical line extending up from the rear bumper where it wraps around to the side. I have the side chrome and the emblems are 2-5/8" above the chrome. On the passenger side again 2/5/8" from the E to a vertical line extending from the rear bumper and 2-5/8" above the side chrome.
