[HPCOBRA]

I am doing a rebuild on a CR from the early 90’s. I noticed that near the dash the body behind the windshield wraps around and ends short of a piece that comes up from what I believe is the cowl. You don’t notice it unless you feel for it under the return lip by the dash. It looks like a perfect place to inject in the minimal expanding foam that comes in the BLUE can for windows and doors. Has anybody tried this?
