I'm sure it's the same as a lot of other cars Canso/Nova/Impala etc. Hard side up/fluffy down....have seen a lot of other posts asking the same question on other sites. I had to ask when I did mine. I just put some seam sealer on underside of hood and set in place so that it wouldn't fall out. Sure someone will chime in thats 100%
fluffy side down. Insure the you glue to the hood. It also tucks under the hood bracing. If not glued the vacumn created by the engine will suck it off.
NOS, what product do you recommend to glue to the hood? Spray on contact cement? Silicone? Or? The insulation is quite thin and doesn't fill the thickness of the hood, so it seems a continuous adhesive like contact cement might be best to hold the entire peice taught against the sheet metal?
I've always wondered about hood insulation. I'd like to put it in my 2+2.
Was it an option you selected when the car was new ?

At that time it was included with certain trim levels or models. On the 67 Beaumonts it was included on the Custom and the Sport Deluxe but omitted on the base model. On your 68 Pontiac it would have been standard on the 2+2, Parisienne, and Grande Parisienne.
It wasn't until 1974 models that one could add the quiet sound group as Acoustical Insulation Pkg option - RPO BS1
