Did the 98 use any trunk lid insulation? Mine shows no sign of any, never noticed any for sale, but other makers big cars had them.

Trunk lid insulation? Whatever for? The purpose of insulation under the hood is to deaden the sound of the engine to make the car overall sound quieter. The purpose of insulation in the roof and doors, if there is any, is to make the passenger compartment quieter and to keep heat in in the wintertime and cold in in the summertime for the comfort of the passengers.

But there is no engine in the trunk, and no one rides in it. It is not a heated nor cooled space. So what would be the purpose of insulation?

I saw no evidence of ever having it, but other makers did.

Mine has.

I know at least Olds and Chevy used it, and would expect it was common across GM, at least on higher level models. May not have been noticed because it was thin like an asphalt shingle and painted body color? Here's a article from Eckler's Classic Chevy.

I have a 65, maybe discontinued before then. If it was original under lid skeleton, certainly not used in 65. Maybe used to isolate skeleton from lid, later replaced by the caulk/glue stuff. Maybe used to keep lid from rattling against skeleton.

Must have ended in the early 60s. We had a 64 Starfire back in the day and I don't recall seeing it on that car either.

Just in case one if the nine bodies in the trunk is still alive, it muffles their screams.

Ha ha, that's pretty funny!
My '61 has the insulation as well.
