Al, You and your “exact originality”, and you were going to buy a jute set. Glad you are feeling good. Duane
I bought some Dynamat Dynaliner 1/8" foam and installed that on the cardboard piece instead of the jute. Was worried about mice and jute. Did the same under the package tray. 1/8" dynaliner foam stuck to the bottom of the package tray.
Excellent choice! I'm looking into the Dynamat on the inside of the roof before I replace the headliner.
See this thread on roof insulation. I did the same. Used some Noico sound deadener (instead of dynamat - went cheaper route) and then 1/8" dynaliner over it instead of the jute. I wound up putting actual dynamat on the floor though. https://www.v8buick.com/index.php?threads/roof-insulation.379063/#post-3320199
