While the silicone is drying, we turn our attention to those broken A/C vents. Here’s the type of tip you’ll only find in Mopar Muscle. Do we scour the countryside looking for E-Body A/C vents? No. We just go to our local wrecker, and pull the A/C vents from a common 1971-74 B-Body. The vent louvers can be removed by pulling the pins on the outside pivots, then sliding the center pivot to the right and then left to remove them. The vents are a drop-in interchange. Take care not to lose the spring clips, which keep the vents from flopping down.
