I know what you mean, I think it's just that there's better products around now to apply to the exterior for purely protection, and the sound deadening properties of the Gravitex etc are also pretty good when combined with deadening the interior. If you want to replace the foam though, when I used to work in Air conditioning, we used a polyethylene foam for the same function, as long as it's closed cell it should be fine. I suppose you could even get the self adhesive stuff and stick thin rubber/plastic sheet to it to give it more mechanical strength.
Something like this would prob do the trick

Most tend to lean towards sound deadening inside partly because of limited access (ideally with gearbox out) and the hassle of cleaning and treating the surface you intend to bond to. I'm not convinced its worth the effort to be honest.

I agree but as the box is out and it's all cleaned back an painted I'm looking into it

I fitted maricoustic foam to mine, held in place with the original wires.
