Need some advice. I have a 70 Duster and I am instaling a MSD 8728 rev limiter. I want it in the interior and not under the hood. I have looked into the glove box and if nothing else I will put it there. However there is a vent door under the dash that would bring fresh air to the unit and it is small enough to fit. Does anyone see any problems with this. Any advice would be greatly appreciated. Thanks.
