63 Dart hood,insulation, bumpers

There are a set of holes across the inside/front of the hood that are for the seal that goes between the hood & front cowl/radiator support area.

This seal influences air flow thru the radiator by providing resistance to flow up and over the radiator...effectively increasing the efficiency of the radiator. There are other less important reasons.

If you want a large detailed picture of the seal applied to the hood send me a PM with your email.
