Was there an under hood insulation pad attached to the underside of the '72 GTX hood? Mine seems to have holes for one, but then again, maybe all hoods had the holes to make it easier for the stamping plant.

If mine did it hasn't been there in 40 years.

Thanks. That is what I thought. The pad might have been put on the more luxury Satellite models but not the performance models.

Nope came with pad except for air grabber. Pad is to drop down and smother an engine fire. For $40 cheap insurance.

Well, now I am confused. One says without a pad and two say with a pad. Any other opinions?

I don't know the '72s. But for my 1970, underhood pads weren't available if you had an air grabber. Otherwise they were optional.

My build sheet is coded for unfercoating could find nothing for underhood pad. If anyone has it on their build sheet and can post the location I will look again. But like I have posted have owned it for 40 years. If the pad was damaged when I bought it may have just pulled it a threw it away.

J55, Undercoating “with hood insulator pad (where applicable)”, was available as an option across the model line in ’72. If your car is not factory undercoated, it likely did not come with a hood pad. If it has factory undercoating and does not have an Air Grabber, it likely had a hood pad when it left the factory.
As @72RoadrunnerGTX and @flypaper has stated, cars equipped with the J55 option would have the car coming with the noise suppression package. This consisted of the under hood insulated mat and full undercoating of the underside of the car. Cars ordered with the Air Grabber hood would delete the under hood pad.
If your car came from the factory with full undercoating on the underside of the car, then it had the J55 option. With this option, the underside received a VERY HEAVY coating of the undercoating material. This basically coated most exposed areas. It was not pretty, but very effective.
All of the production cars should have gotten factory sprayed undercoating in the wheel houses, both front and rear. It was not uncommon back in the day for the selling dealership to offer more undercoating or sending the car out to have it "Ziebarted" at additional cost. It was another way for the dealership to upsell a product quite popular years ago.
With guys restoring cars and wanting the underside to look clean and fresh, many factory undercoated cars now feature either a fully painted or the primer look with paint overspray.
In my opinion, very rarely do you see a factory undercoated car restored correctly. The original undercoating appearance is very difficult to reproduce and is more difficult to maintain.
As with anything with assembly line production, you never know what may have gotten out the door. I say that in that I have learned to never say "Never" with these old cars. But hope that this gives some insight into what I have seen in my years of being around these cars.

Same code for 72-74 cars. Included with undercoating except with N96

Thanks to everyone for the help. That is a lot of good information for me now, and for anyone looking to clear up this subject in the future.
