HouseCallAuto 2/17/2012Yes, that part # is correct but ACDELCO also has an upgraded version @ part # 18B147A - the A at the end is for "Advantage" do not know specifically what the advantage is however the drum costs a little more but it's your call, either one is fine and they are both genuine ACDELCO parts. If you look at the inside door jam of your van you will see a decal with a n=bunch of three digit codes. This is a RPO decal Regular Production Options. You will likely see the code JD7 indicating the brake system your van was built with. The two parts numbers fit JD7 brake systems. Just confirm the JD7 on your decal.
