Interesting topic. Don't think I've seen sound deadening discussed before here. Restoring (in my imagination) my (so far non-existent) 400, I have thought about insulation, both for sound and heat (keeping cool as well as warm.) If I had to re-do an interior it would be a given to do this.

But I was wondering how much insulation, if any, is already between the headliner and the roof from the factory. This is a critical area, especially for keeping cool without AC. I've read experiences of restorations of other makes regarding headliner insulation and very good results for keeping interior temps down in summer. (However, I think it would be senseless to tear out a good headliner and replace it just to add insulation--especially if there is already some in there.)

I know it's never too hot or sunny in Arizona, Kevin, but thought you might be considering this application for your 400 if the headliner is in need of replacement! Sorry, I don't know what phase of work you're on with your 400.
