I used a gasket scraper that was just the right size to get down in the groove....but something else will work just as well, maybe a screwdriver??
When I replaced the one on my 37 I went back to an original cork type gasket. The first one was a type of rubber and never sealed good.....even with the spring under the dash cut tighter. I may have to replace the cork once more in my life time but the vent presses down into the gasket and seals better.
Just my thoughts.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
