Pierre have you actually ordered these from Majestic?
If you look at the diagram it shows the old syle tumblers....not the new style tumblers. I checked out an 88 Civic on majestics site and came up with same part numbers. Majestic has made a mistake on the Element listing.
I have verified that it's a mistake and they do not sell the tumblers for the E. They only sell a complete lock.
