Cab Insulation

[damnyankee36]

I would like to soundproof the cab of my 66. In addition to installing matting on the firewall, rear, doors, etc, I am trying to figure out the best way to insulate the roof.

I am invisioning applying expanding foam between the the roof and the interior panel. Has anybody tried that? I figure if there is an escape route for any excess foam, there shouldn't be any sheetmetal deformation or swelling from the foam expanding too much.

Any other ideas?

Thanks!
