everytime i go to AutoZone or Kragen for little things, and they ask for my information (97 disco) it pops up in their computer that i have a 3.9...which i dont, i have the 4.0 engine..so i always have to tell them i have a 98 instead for their computers sake...but didnt they start making the 4.0 in 96? my buddy's 96 is a 3.9 though also...but i've seen 96's with 4.0's..anyhow..anyone else have this problem?
