I too use this cover, I took the additional step of adding a second layer of the neoprene on the rear side of this cover to provide reinforcement of this cover, now 99% of the air stays out... very nice in the cold winter use and will be a relief in the summer heat!
This seems to work very well. No holes to drill. I used the existing bolt holes and converted to studs. I will see what more will cost I paid $125.00 with computer time. I think a duplicate will be $75. I do have more rubber I will donate

It mounts on the dash using existing screw holes and includes a thin rubber gasket behind the plate. it looks good and blocks much of the cold air intrusion through the shifter gates.
Larry actually sells the shifter plates for $80 w/shipping included.
