I have a 1970 El Camino with an interior code of 752. According to my code book this is for a 69 300 based interior. The interior in my 70 is just this. It has a rubber floor mat and different door panels. The panels are black with a thin chrome trim on the top and a 1" wide white colored insert about 3" below the chrome trim. Another strange thing is that the tailgate has the emblems of a 69 El Camino. The red/white/blue emblem is below the chevrolet script and the script is in cursive. The model # is 13480. Can someone explain to me why this would be. Also does this make the El Camino rare? Or worth more than one that would be comparable? I have the vehicle for sale and would like to know about these things. Thank You.
