I stuck a piece of Siless insulation to a piece of Thermo-Tec 13590 24" X 48" Adhesive Backed Heat Barrier. Slide the shifter shaft through the hole. Now when you move the shifter the insulation moves with it. Make the insulation long enough that it covers the open slot over the complete range of shifter movement.Has anyone figured out what to do with the air coming in the gearshift lever!
