I'm going to shave or fill the cowl vents on my 66 coupe,what is the down side to this mod ? I know on the drivers side it is an air vent,passengers side I'm not sure, I will be running AC and heater,any thoughts ?
I want to do it, Vintage Air kit uses recirculated air anyways. Looks much better and then you won't have that unsightly nastyness (at least I do) under the grates..
