63 Dart hood,insulation, bumpers

The insulation side goes toward the hood.
Not sure about the "bumpers" you asked about, unless you are talking about the adjustable bolt type stops that the hood rests on at the corners.
Or some cars had little rubber things along the inside of the fender that the hood rests on.

I didn't have any hood insulation on the hood when I bought the car. I just painted under the hood , and about to put insulation on the hood. Does the black part go towards the hood, and isulation towards the motor or vise versa. In addition can anyone show or tell if there are rubber bumpers in the hood, thanks in advance, Jim
