I see negative reviews about installing the dust cover here. It's extremely easy. You will need a length of 2 3/8 inch OD hose and when working with Mopars this hose barb comes in handy for installing other seals. So keep him with you. First, there is an "Install inside" mark on the trunk. Position the inward-pointing arrow. Second, I put some tape on the bottom edge of the pipe nipple to cushion the bottom edge of the pipe that comes in contact with the boot to protect the gasket. Now simply put the boot on, then place the tube over the seal and tap until it snaps into place. Takes about 1 minute and fits perfectly.
