The heater box is under the dash so the seal is also on the dash side to seal heater box to firewall. #3963725. There's nothing on the engine side, just the heater core pipes coming through, each with a sponge seal around them as well.

Some sell a reproduction, otherwise just use close-cell neoprene with adhesive backing on 4 sides.

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
