Tailgate Window Lifter Seal 1979-1991

A: Clean the glass to remove all sediment and debris, then wipe down with denatured alcohol (or similar) to remove all wax and grease. Set down several towels on a flat sturdy surface (counter or kitchen table, etc), and set the glass with the bottom facing up. Sandwich the seal over the bottom of the glass. Then set the channel over the seal, and gently tap down using a rubber mallet. Remember to go slowly and be VERY gentle. Keep tapping a little at a time all the way across, and then work your way back. We recommend tapping just a few times in each section going from side to side (ie: don't try to fully seat one section completely, just do a little at a time with multiple passes side to side until fully seated).
